3kW, Convection Cooled, Ultra-Crude Industrial Power Supply - Power Electronics Technology
The Absopulse HVI 3KP-V9 is a unrefined, convection cooled power supply designed for driving low voltage 24V, 48V, or 125Vdc equipment in severe environments where fans or self-conscious air are not practicable, and high instantaneous power is required. Typical applications include electro-mechanical lifting and positioning accoutrements, winches, pumps, and a broad range of other industrial machinery and equipment. In these applications, the use of batteries is often not feasible because proper subsistence cannot be ensured, and critical battery power may not be available when needed. The power supply accepts a 400Vac, 3-phase input and delivers between 2,500 and 3,500W, depending on diligence requirements. 125Vdc or higher DC-inputs are also available. Typical conversion efficiency is 85% at full load depending on input/output configuration. It is built with rude internal power modules, each separated by a built-in redundancy diode. The internal redundancy diodes allow for a number of units to be connected in duplicate to achieve higher output power. Regulation is better than 2% from no load to full load, including redundancy diode. Each internal power module is encapsulated with a thermally conductive MIL-state silicon rubber potting compound with UL94V-0 flammability rating. The potting of the internal modules ensures effective heat give to the fins. The HVI 3KP-V9 operates over a 0°C to +50°C temperature range for full specification with no requirement for temperature derating. Requirements for wider temperature ranges can be accommodated. The input and yield are filtered for low noise. The power supply is designed for compliance with EN/UL60950-1 and equivalent safety standards. Full electronic aegis, low component count, large design headroom and the use of components with established reliability contribute to an MTBF of a minimum of 90,000 hours at 45°C. .

Semitrex reveals Tronium technology for force saving power designs - EDN.com
We pre-eminent discussed this new technology in previous articles on EDN in 2015 ( Switched-capacitor AC-DC/DC-AC converters boost efficiency in power supplies ), and earlier this year when Michael Freeman, CEO/CTO for Semitrex wrote Coach side... On June 7, 2016 Semitrex opened a UK office, the London Integrated Design Center, focused on Inverter Technology which is so notable to the UK’s Renewable Energy Goals as well as the world’s goals in this area. This London-based design team will be concentrating their pattern efforts on an Intelligent Inverter Supply System on a Chip (ISSoC ) for renewable energy goals mandated by the European Amalgamating (EU). In spite of all the Brexit turmoil recently, this... Semitrex technology will also boost the UK’s semiconductor export market, thereby help alleviate the UK/EU relationship. Freeman’s designers have determined that not only is their process excellent for power converter designs, but also for the reverse: the essential power inverter by using their switched capacitor technology. This architecture can have significant reduce power effects upon micro-inverter technology which is especially needed in solar applications. AC/DC and DC/DC Technology capabilities: A high voltage up-end b stay-off, “dial-a-voltage ” Twin Power Supply System on a Chip (with internal powering of the MPU), the TRONIUM PSSoC is a multichip module that can be set to crop from 1. 8V to 48V, and... At TRONIUM’s core is an application-specific integrated circuit (ASIC) customized for a particular use, rather than intended for heterogeneous-purpose use. This technology uses a new power conversion method (Capacitive Voltage Reduction) which produces greater than 90% expertise at all loads. The new technology automatically sets to the “mains” grid power supplies around the world, and has a “sleep” mode, which uses only ½ milliwatt of standby power in the U. S. and less than 1 milliwatt in the residue of the world, solving the so-called... The TRONIUM ICs use an innovative Muxcapacitor™ (MXC) voltage pre-regulation, that provides voltage reduction using cascading capacitors. Most converters in today’s power architectures use extreme transformer winding ratios to achieve large step‐down voltages. The TRONIUM MXC technology drops the voltage by using a capacitor series. Lower conversion ratios translate into higher energy efficiency. MXC pre-regulation enables a lower primary converter input voltage. With TRONIUM MXC technologies, this Laptop charging seal is capable of delivering power at above 90% efficiency from full output (120 watts) down to less than ½ milliwatt in drowse mode. This avoids wasted power (vampire losses) when a laptop is fully charged, powered down, or unplugged from the charger. Semitrex’s Tronium power stock architecture gets rid of the need for transformers, instead using capacitor banks to reduce voltage. Transformers are known for their very low skilfulness at low currents such as a solar inverter would have on a cloudy day. The London design center will endeavor to create an ISSoC up-converter for solar applications with damned high efficiency and super-low stand-by power through their cascaded capacitor.

Primary Solar Moving to a Medium-Voltage DC Power Plant Architecture - Greentech Media
Outset Solar is making a fundamental change in the architecture of the big solar power plants it builds and operates. CEO Jim Hughes has made repeated claims about tariff reductions at the leading integrated solar power provider, saying, "We have a technology roadmap -- by 2017, we'll be under $1. 00 per watt fully installed on a tracker in the western Merged States. First Solar CTO Raffi Garabedian recently outlined some of the paths the company is following in order to hit that low number -- including improved stall efficiency, new module form factors , one-axis trackers and a new solar architecture that... That's medium-voltage DC (MVDC) -- and Garabedian exact the new approach at First Solar's recent analyst day. MVDC Garabedian called MVDC "a completely new, radically game-changing power undercover architecture for solar. Multiple strings of modules are combined in combiner boxes where all of that energy is aggregated in parallel, and fuse-protected, and then sent at the end of one's tether with feeder lines to power conversion stations. That transmission of energy is done at 1,500 volts today with our 1,500-volt inverter methodology. "Each power conversion station is a combination of an inverter and a transformer that steps up the voltage roughly to 35 kilovolts, which goes to a PV combiner change gear and then onto the substation and onto the grid connection. That's how power plants are built today," Garabedian continued. "We're looking at changing the gang of elements in this power plant, reducing the number of parts and improving the capacity factor of the energy generation of the plant. The way we're prospering to do this is what's called medium-voltage DC. By replacing the combiner boxes here with DC-to-DC converters that step up the voltage from the strings to roughly 10x the string voltage of 1,500 volts, we can dramatically... "We also conduct to bear grid control and support functions that are already available in these large-scale DC-to-AC converters, which are not available in standard PV inverter systems. The procedure hinges on a new component, and the new component is being designed and developed by First Solar with partners. " This DC-to-DC converter "looks kind of like a transformer that you might see in your neighborhood, and it performs that voltage conversion and power-apex tracking function that used to be done in the PV inverter. It also supports the same functionality as the combiner boxes and spreads some of the power conversion into the department," Garabedian added. We can reduce the amount of labor in the field, and we can reduce the energy losses in the power conversion systems. "To put this in background, let's talk about power conversion stations, inverters and transformers. With a 1,000-volt system, a typical 100-megawatt power put would have 100 power conversion stations that have to be put out in the field, installed, commissioned and brought up. [With] a 4-MVA system like our 1,500 volt architecture, that tot up... "With MVDC, there is one power conversion station -- a single centralized power conversion station that's integrated.
