Its key idea is that integration of GTO with improved structure, antiparallel freewheeling diode and gate drive circuit, then connects its gate drive by low inductance.
In the circuit shown in Figure 5-1, the gate of the SCR is connected through a resistor and diode directly to its anode.

This paper proposes a new gate drive method for active clamped quasi resonant converters. Instead of a digital delay circuit, only a resistor and a diode are added to produce correct drive waveforms.
