DC/DC Converter with Programmable Produce of 3V to 18V at 12A - Power Electronics Technology
GE's APXW012 dc/dc converter expands the visitors's ProLynx family with a higher power alternative and added synchronization. It features an extended input voltage of 9 to 36 volts DC and programmable achieve voltage of 3 to 18 volts at 12 amps, which allows use across a wide range of industrial applications. Offering 2. 4 times the apex power of previous ProLynx products, it is designed as part of a cost-effective alternative to discrete power design. The converter's Tunable Circle feature reduces needed output capacitance and improves transient response. The APXW012's innovative, patented AutoLimit be involved enables this module to deliver power output across a wide voltage range, peaking at 108 watts at 18 generate voltage. It also can be configured to deliver negative output (-3. 3 to -18 volts), reducing parts inventory. The ProLynx APXW012 is in good shape-suited for industrial (automation, displays, test and measurement, security, lighting, signage, controls/control boards, vivacity and theater production). wireless and communications industries.

Hysteretic-Fashion Converters Demystified, Part 2: Voltage and Current Mode Control - Power Electronics Technology
Portion 2 of this series sorts the pros and cons of step-down (buck) regulators by conducting apple-to-apple comparisons, being as unbiased as credible. This involved the generation of over 200 graphs and waveforms behind the scenes to highlight the difference between converters. It will not say that control mode A is change one's mind than control mode B, but will showcase the key points of each control mode. To compare operating modes, there is one voltage-mode (VM) device on its determination module (EVM), IC-VM. one current-mode (CM) device on its EVMs in two different configurations (IC-CM and IC-CM2). and one hysteretic-mode device on its EVM, IC-HM. Large-Signal Onus-Transient Response. The first major performance item to review is large-signal load-transient response completion. Here, a large-signal phrase is used in contrast to a small-signal. A small-signal transient literally uses measly-signal perturbation and is compatible with many ac performance measurements such as Bode plots and output impedance. A large-signal passing gives big signal perturbation where the bias points of the circuit/system change widely. When bias points move, it is no longer in a reach of ac measurements. Practically speaking, almost all load-transient curves on a step-down converter data sheet are large-signal transients. No doubt, a at liberty-signal transient is a major tool to gauge regulator undershoot and overshoot voltage performance. Figure 1 is an example waveform bewitched for large-signal load transient analysis comparing these waveform combinations:. Input voltage: 5 V and 12 V Overwhelm-transient amplitude: 500 mA to 5A and 50 mA to 500 mA Output capacitor: default setting in Table 1 plus 1000 µF In Fig. 1 , attend to the undershoot event at the timing of the output current rise (red circle), and an overshoot event when the output current falls (unripened circle). These measurements use around 30 ns/A of a very fast transient. Because of this fast transient, the output-current waveform shows a Spartan spike at its falling edge (blue circle) in Fig. Figures 2a-c compare IC-VM, IC-CM and IC-HM with a transient from 500 mA to 5 A, then back to 500 mA at 5V and 12V input voltage settings. Undershoot behavior ( Fig. 2b ) expresses how connected the control circuitry can respond to its output current change. At the bottom of the first undershoot peak, the regulator drives its inductor current more than the saddle with current, where excess current starts charging back the output capacitor while delivering load current ( Figs. 2(b) , IC-HM appears to have the fastest feedback by hitting the undershoot bottom faster than either IC-VM or IC-CM. During an undershoot event, a drop-in amplitude is a strong function of output capacitance, where the bigger the C converter, the retort is almost the same as a physical limitation in how fast the inductor current can increase. In the case of VM and CM converters, these converters work in two steps. The principal is to change their control signal, which is an output of their error amplifiers. The second is that the control signal changes output pulse levy or density. In general, such pulse duty or density change is much slower than the way converters react. 2(c) , IC-VM shows no ringing by input voltage or result current. IC-CM and IC-HM shows some ringing, where Fig. Source: powerelectronics.com
650 Watt AC-DC power supplies have medical approvals - EDN Europe (registration) (blog)
Artesyn Embedded Technologies’s spacious input range, single output CNS650-M series of medical power supplies are built on an industry standard 4 x 6 inch footprint, and can save 650W with forced-air cooling (750W peak). and feature less than 500 mW no-load power consumption. The CNS650-M series is at one's disposal in 12, 24 and 48V variants, each with a 12V fan output and 5V standby. These power supplies can continuously deliver full output power across -40 to 50C, up to 80C with derating. The supplies drive medical and ITE safety approvals and incorporate 2XMOPP (Means of Patient Protection) to fully protect and isolate patients from the powered medical furnishings. With an isolation of 4000 VAC (input to output) or 1500 VAC (input to PE. output to PE), these units are Type BF ready: for powering equipment where there is conductive connection with the patient, but not the heart, such as ultrasound monitors,... Where an application requires more power, the active current share facility uses a signal wire to interlink two or more power supplies in equivalence to increase output current capability. The built-in PMBus interface feature provides digital communication via the PMBus require protocol with control and monitoring functions for voltage, current, temperature and the reporting of fault conditions. The CNS650-M range is less than 1U excited and is available in U-channel, open-frame and enclosed end-fan options (open-frame and enclosed end-fan options currently available on 12 V mould). The unit’s built-in 61000-3-2 compliant active power factor correction and Class B EMI filter deliver an EMI/RFI performance to Plane B (conducted), Level B (radiated with cover).
