You can combine a carefully chosen op amp, a low-threshold P-channel MOSFET, and two feedback resistors to make a rectifier circuit with less forward drop than a diode (Figure 1). The rectified output ...

Yesterday’s idea for a Cuk converter synchronous rectifier drive (right) seems to work, according to my use of LTspice. Yesterday’s idea for a Cuk converter synchronous rectifier drive (right) seems ...

ORing diodes are a necessary evil of high-reliability systems. They're used to isolate redundant power sources so a failure of one source won't bring down the entire system. Several inherent problems ...

When powering a battery operated circuit, the experimenter must make a decision: either take his chances (Murphy loves this one), or opt to add protection in the form of a simple series diode.

The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance at little or no ...

Having thought up and simulated a drive circuit for the synchronous rectifier in a Cuk converter, I thought I would wrap it all up by appling the things I learned to the original circuit – a high-side ...

IRVINE, Calif., June 28, 2022 /PRNewswire/ -- Elevation Semiconductor, a high-voltage power conversion solutions developer, announced today the release of HL9750, a device belonging to a family of ...

STMicroelectronics’ SRK1004 synchronous-rectifier controllers save space and increase efficiency in the secondary side of active-clamp ...
