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 – ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

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 ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

Power supplies that use diodes to rectify an ac voltage to obtain a dc voltage must deal with inherent inefficiencies. A standard diode or ultra-fast diode can have a 1-V forward voltage or higher at ...

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 ...
