SMT current-sense transformers measure up to 30 A
TDK Corporation presents two new series of EPCOS SMT current sense transformers for power electronics. The various types in the B78417A* series are based on EP7 ferrite cores, have compact dimensions of just 10.6 mm x 12.2 mm x 11.0 mm and are designed to measure pulse currents of up to 20 A. The maximum […]
New 480 volt temporary power distribution system with transformer
Larson Electronics has announced the release of a new portable power distribution system that converts 480 volts AC three phase electrical current to 120 volts AC and 208Y volts AC. The MGL-100C-480-15K-120-208Y-12X20 temporary power distribution system from Larson Electronics provides a safe and reliable way for operators in industrial settings to tap into and utilize […]
Compact Current Sense transformers sense up to 20 A
Coilcraft announces its new CST7030 Series of surface mount current sense transformers which measure just 5.2 X 7.0 mm (with a max height of 3.0 mm) and sense up to 20 Amps of current at frequencies between 10 kHz and 1 MHz. Typical applications include load current measurement and control in switching power supplies and […]
New mobile power distribution center
Larson Electronics has added to its extensive range of industrial grade lighting equipment with the release of a mobile power distribution system that steps down 208Y electrical current to 120 volts AC. The MDC-208Y-100MB-8X120 temporary power distribution system from Larson Electronics provides a safe and reliable way for operators in industrial settings to tap into […]
Heavy duty mobile power distribution substation features dual 75 KVA transformers
Larson Electronics has announced the release of a heavy duty mobile power distribution substation that features two 75K VA transformers with pin and sleeve connections. The MGS-1X480.200-2X75K-2X208.200 power distribution system from Larson Electronics is designed to provide operators with one 200 amp male pin and sleeve plug at 480 volts and two 200 amp 208Y […]
Top power electronics threads on EDAboard.com – November
3V – 5V high current 150A power supply – I have been asked to generate a 100A RMS precise sinusoidal current. It will have negligible burden/load. Luckily I’ve done something very similar in the past where I used a LEM sensor, a dsPIC33, and an inductive load and a current-controlled PWM inverter based on a PI […]
Top power electronics threads on EDAboard.com – August
Phase shift full-bridge SMPS is massively over-hyped? – The Phase Shift Full Bridge (PSFB) converter is a hoax. The LTspice simulation (Editor’s note: see post for file) of a “plain” full-bridge SMPS bears this out. PSFB claims to be able to reduce switching losses compared to the “plain” full-bridge SMPS. However, the PSFB does have turn-OFF switching losses, just […]
Transformers optimized for Fly-buck converters
Premier Magnetics, global producer of high-quality magnetic components, has introduced a line of transformers specifically designed to complement the Texas Instruments LM5017 family of Fly-Buck converters. The Premier Magnetics Fly-Buck transformers™ topology and electrical characteristics are designed to provide fast and simple implementation of the Fly-Buck circuit for two or four isolated outputs. The devices […]
Gallery: Scenes from the IEEE ECCE conference
The IEEE Energy Conversion Congress and Exposition took place last week in Pittsburgh. The clear trends based on exhibits on the show floor included a lot of interest in SiC power devices and in alternative topologies for inverters. Here are a few of the more interesting sites we encountered there. SiC on display The Center […]
