[Electronoobs] is using some brushless motors to make a DIY wind turbine. His recent video isn’t about the turbine itself, but a crucial electronic part: the three-phase rectifier. The reason it is so ...

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 ...

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 ...
