The … WebJan 1, 2016 · I tested this rectifier in LTSpice. Using only a resistive load it worked perfectly, generating a full-wave rectified current over the load resistor, with a very small voltage drop in the transistors (depending on on-resistance, not on the body diode forward voltage). Then I added a capacitor to make it a continous DC current.
