Diode DC Voltage Source The output voltage is proportional to the duty cycle of the MOSFET. 12 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

WebThe diode is initially forward biased carrying a positive forward current. As soon as the gate-source signal (V GS) goes high to turn on the top side control FET, the body diode turn-off process of the low side FET is initiated. The diode current rolls off at a constant slope (di/dt) to zero and then reverses the direction. The negative current ...
