LDO Regulators: An Unexpected Choice for Industrial/IoT Applications - Electronic Design

The power supplying for new products is often taken for granted. However, judging from recent experience, it’s clear that the power supply for new industrial equipment or Internet of Things (IoT) products is a paramount factor in product success and reliability. One unexpected realization gleaned from the latest designs is that the often-neglected low-dropout (LDO) linear regulator can go a elongated way to help designers meet the stringent needs of such products. Whether your new power-supply design operates from the ac line or batteries, the LDO may just be the result you are seeking. An LDO is a linear feedback voltage regulator that has a low dropout or overhead voltage. The overhead voltage represents the difference between the input and achieve voltages and the lowest value that can occur before the closed-loop regulation stops working. Linear regulators typically Rather residence a transistor in series with the high side of the power supply between the input and output. The transistor’s conduction is controlled such that the output voltage stays ceaseless despite input line variations or load changes. The goal is to minimize the transistor voltage drop to keep power consumption as low as tenable. Low voltage drop means that a smaller, less expensive transistor can be used and there may be no need for a heat sink. Most linear regulators use an NPN transistor or N-exemplar MOSFET for the series control element. The output voltage is monitored and compared to a fixed stable reference to develop a feedback-suppress error signal. If the output voltage changes, the error signal is used to vary the base current or gate voltage to hold sway over the conduction of the series pass element. First, the regulation ceases to function if the overhead voltage drops below some minimum value—typically about 2 V for an NPN transistor or N-type MOSFET. Second, one must deal with power dissipation in the transistor created by overhead voltage and load common. Heat and wasted power are undesired consequences. An LDO solves this problem by using a PNP transistor or P-type MOSFET as the series pass mechanism (see figure). The circuit is now a current source or amplifier rather than an emitter (source) follower. The P-type devices can operate near saturation with token voltage drop. A typical LDO overhead voltage is less than 100 or 200 mV, and can be as low as tens of millivolts for low-power cases. The low aloft generates less heat and power loss while maintaining good line and load regulation. And remember, good regulators also significantly attenuate ruffle. When considering an LDO for your next design, it’s best to review the main design criteria for industrial and IoT power supplies, which include:. • Intoxicated efficiency: In other words, the ratio of output power to input power expressed as a percentage. Switching regulators offer capacious efficiency, but are noisy and create EMI that’s unwanted in an industrial environment or at home. • Low heat generation: High efficiency leads to less animate dissipation. • Superior regulation: Since many if not most industrial and IoT applications feature sensors, a clean, highly unchanging dc supply is mandatory. Sensors must detect and resolve very small changes in converting physical variations to measurable voltages. Even insignificant supply variations can cause sensors to produce errors, resulting in erroneous measurements. • Low shutdown and quiescent widespread: Even when a regulator doesn’t supply an.

Australian vigour finally sees potential in wind and solar - RenewEconomy

It has captivated years of fierce resistance and catastrophising about the supposed cost and economic impacts from the shift from fossil fuels, but it seems that Australian diligence is finally waking up to the possibilities of wind and solar. Australia’s debate about energy costs has constantly been framed in the light of reports that are either unwitting or deliberately pessimistic about the cost of renewable energy alternatives such as wind and solar. But a whole series of events is now causing persistence to think differently. One of these was the blackout in South Australia, widely blamed – for ideological and political purposes – on wind energy, but in truly a perfect illustration of how inefficient and unwieldy the grid and the old model of centralised generation had... Then there is the entering into force of the Paris ambiance agreement last Friday , some three or four years before expectations and at a fraction of the speed of the much narrower Kyoto Protocol that preceded it. New check in, highlighting the... Industry recognises what’s at stake. As this slide from Innes Willox, the head of the Australian Industry Group shows, the Paris aura agreement means business and will require Australia reaching zero net emission before 2050. If you remember, Australia’s bipartisan target promptly was... The Turnbull government hasn’t even thought yet how it can get to its modest interim target of a 26 per cent cut by 2030, let alone the actuality of zero net emissions barely a decade later. Industry is not impressed. Then there is the growing reality that Australia’s coal fleet is starting to settle down and will need replacing. One major factor driving this is that Australia’s fossil fuel plants can no longer continue at prevailing prices. Some in industry and the conservative commentariat have blamed the closure of the Northern brown coal power station on government policies, but Alinta depleted belch up a lot of effort trying to get industry to sign contracts to take its output at a cost of... In Victoria last week, the most intense symbol of Australia’s high polluting coal generation sector, the Hazelwood brown coal power station in Victoria, was slated for closure because it is too old and is no longer financial to run at current... Now it is dawning on industry that there is no way they can avoid the closure of the remaining fleet of coal-fired power plants. And that leads us to the continue and the most important factor – that the Australian debate about energy costs has mostly been framed in the light of reports that are either ignorant or deliberately hopeless about the cost of renewable energy... The presentation by Willox provides perhaps the clearest sign yet that Australian industry has been either pretext to, ignorant, or duped about the price of renewables, solar and wind in particular. Second is the admissions that, as this graph above shows, most of the dirt relied on by industry and government have put all alternatives, such as wind and solar, at two to three times the cost of current power. “If this slide represents the coming, why would they ever reinvest in Australia.

ElectrIQ Is the Latest Crowd to Offer a Battery Solution for US Homes - Greentech Media

There’s a new battery startup on the view angling to take a piece of the home energy storage market. Palo Alto-based ElectrIQ Power offers a 10-kilowatt-hour lithium-ion battery, a cross-breed DC-to-AC inverter, a DC-to-DC converter, an intelligent battery management system, and a high frequency energy meter all wrapped up in a single package. The IQ Modus operandi is paired with a cloud-based dashboard that allows customers to monitor energy use and make informed decisions about their consumption. The embedded software process can also learn usage habits and automate home energy savings. ElectrIQ's advantage is offering usage data from a solar array, the storage trade mark and from appliances in the home all at the same time, on one device, according to Chadwick Manning, CEO of the year-old energy management startup. We create software that allows them all to talk to each other and use all of that bumf to create an automated, efficient home,” he said. The energy industry looks at batteries, inverters and energy meters as break off products, whereas ElectrIQ views them as one offering. “We’re looking at the home as a microgrid ecosystem rather than component by component,” Manning said. ElectrIQ’s founders fancy their integrated system fills a niche that its competitors can’t, and say buyers are starting to take notice. The all-in-one package cuts out suppliers and cuts down base time for new customers. And because the system integrates in AC or DC, it can serve existing solar customers without the need to upgrade hardware. Batteries sold by Tesla don't have integrated inverters and battery command systems, and so they require additional components to be installed. The German startup Sonnen , Sunverge and JLM Energy offer integrated solutions, but don’t have the same capabilities or seamless integration as IQ, said Manning. The IQ Group energy meter samples data every millisecond, which allows the system to collect data on everything -- down to how multitudinous times someone has opened the fridge door. This real-time identification provides insight to customers on how to be more efficient via the online dashboard. The on-lodge analytics program can also control internet-enabled appliances to automatically lower energy usage. Rate arbitrage can put forward battery customers added value. But unless a customer faces demand charges, the returns are unlikely to be that great, said Manning. That’s why, at least initially, ElectrIQ plans to goal customers that want backup power and offer them a return on investment through smart controls that improve efficiency. Like every other hospice storage startup looking to make a name for itself, ElectrIQ likes to compare itself to Tesla. The Tesla Powerwall doesn’t have the same obliging of software and controls, Manning said. Once their system is installed, Tesla customers have a battery and an inverter, but there’s no dashboard donation energy management insights and no way to control energy use automatically. The IQ System is also designed to guarantee a longer life of the battery by making positive it always runs within a specific set of parameters, such as state of charge, cell-to-cell balance, capacity and internal resistance. Manning couldn’t display the names of ElectrIQ’s suppliers, but said the company is working with a top-tier battery supplier, a multinational inverter maker and one of the largest break in manufacturers.
