WebThe rectifier MOSFET also has body-diode losses. The average body-diode current can be calculated during dead time. The blue waveform in Figure 9 shows the dead time, which is the time between when the high-side FET turns off and the low-side FET (rectifier FET) turns on. We want the average current in the switching cycle. The Web3 to the body diode, D 3, of SR 3. Due to relatively high forward-voltage drops of the body diodes of SR 2 and SR 3, the efficiency of synchronous rectification is reduced. The efficiency loss due to the body-diode conduction depends on the duration of the dead time (T dead) and the forward-voltage drops of the body diodes (V BD). This loss can ...

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.
