We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

STMicroelectronics has released details of BC2 (Back-Current Circuit), their new high-efficiency circuit and dedicated optimized power components design. BC2 is targeted for boost or buck converters – ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

This file type includes high resolution graphics and schematics. In operation, the LT4320 reads the incoming ac voltage waveform and smoothly turns on the appropriate pair of MOSFETs for each half ...

A solid-state device, the gate-controlled, silicon controlled rectifier, or GTO SCR, that can be turned on and off by the application of a signal to its gate can be used in automotive electrical ...

Infineon has put a 650V silicon IGBT alongside a silicon carbide diode in the same TO-247 packages. “Due to a freewheeling SiC Schottky barrier diode, the CoolSiC Hybrid IGBTs perform with ...

For hard-switched power topologies, Infineon is planning a 100V GaN transistors with a integrated Schottky diode. “Due to the lack of body diode in hard-switching applications, GaN-based topologies ...
