Finnish company Enedo Power has turned to GaN transistors to put a 1,200W ac-dc power supply into a 41 x 107 x 206mm (900cm3) volume. Called HDP1200, they run from 85 – 305Vac (de-rated to 1kW below 137Vac) and produce 24V or 48V depending on type, plus a 5V 1.5A stand-by output. Efficiency is up to 95.5%, and a fan ...
Rohde & Schwarz announced a dual-channel 3.6kW precision power supply at Productronica today. Called NGT3622 and rack-mountable, each of its channels will be rated up to 80V or 50A, and resolution (not necessarily accuracy) is “100µA for current and 1mV for voltage”, said the company. “NGT3622 combines two independent 1,800W outputs [which] can be combined in series or parallel, allowing ...
XP Power has launched a host of GaN-based plug-in ac-dc power supplies rated between 65W and 140W. The basic types are: PGW65 wall-mount 65W (0.37W/cm3 – 6.06W/in3) PGW100 wall-mount 100W (0.53W/cm3 – 8.72W/in3) PGD100 corded 100W (0.48W/cm3 – 7.93W/in3) PGD140 corded 140W (0.55W/cm3 – 9.0W/in3) They “are designed to conform to the Power Delivery protocol and are ideal for industrial ...
XP Power has added a digital control option to its HRF15 15W adjustable precision high-voltage dc-dc PSU series. There are three basic models, all 24Vin and all non-isolated: HRF1524S10K0* – 0 to 10kV at 1.5mA HRF1524S12K0* – 0 to 12kV at 1.25mA HRF1524S15K0* – 0 to 15kV at 1mA The main options on top of this are: Positive (*=P) or ...
EPC has revealed a 6kW 800-to-12.5V dc-dc converter with a novel (input-series output-parallel) topology, as part of Nvidia’s 800Vdc data centre power distribution programme. The GaN hemt based proof-of-concept is 8mm tall and occupies <5,000mm2. “GaN is an essential technology for the 800Vdc ecosystem,” claimed EPC CEO Alex Lidow. While Power Integrations proposes a single half-bridge pair of 1,250V GaN ...
Texas Instruments has revealed its proposals for Nvidia’s 800Vdc data centre power supply concept at the Open Compute Summit in San Jose. At the supply end, it described a 30kW 800Vdc Open Rack format voltage source measuring 800 x 160 x 32mm. This takes 480Vac three-phase mains into a three-level flying capacitor power factor correction converter (diagram right), which generates ...
CBM300S is a 300W fan-less ac-dc baseplate-cooled PSU, delivering 360W peak, in a 107 x 85 x 20mm brick. Made by Cinon and available through Relec, the supplies have closed-box construction and can accept power from 90 – 264Vac or 120 – 370Vdc. Different version offer outputs at 12, 15, 24, 28, 36, 48 or 54V. These can be trimmed ...
Power Integrations is showing off its GaN technology with a PSU development kit for solar-powered racing cars, that it is offering free to such teams. “The kit is inspired by a design created by PI’s on-line support engineers in collaboration with the ETH Zurich aCentauri team, whose ‘Silvretta’ challenger-class car is using the design to maximise efficiency in its auxiliary ...
Rohm has released hybrid analogue-digital controlled design for a 24V 4A output mains PSU built around its ML62Q2035 16bit RISC MCU. The design, called REF67004 and implemented on the LogiCoA003-EVK-001 evaluation board, incorporates a critical conduction mode PFC (power factor correction) stage followed by an isolated quasi-resonant fly-back converter. “Analog-controlled power supplies are widely used in small to medium-power industrial ...
ActionPower has released a modular programmable ac and dc power supply and load, aimed at testing photovoltaic micro-inverters. Helion, as it will be called, fits a 3U rack slot and designed to work with up to six output or load modules, which slide in from its rear. These can be ac or dc types, which the unit automatically identifies. “The ...
