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 ...
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 ...
The losses in a bridge rectifier can easily become significant when low voltages are being rectified. The voltage drop across the bridge is a good 1.5 V, which is a hefty 25% with an input voltage of ...
In looking at any buck converter point-of-load regulator designed today, chances are that it uses synchronous rectification rather than a conventional diode for freewheeling. Synchronous rectification ...
