The waveforms of switching process and control voltages: (a) the switching process of switch , (b) the control voltages for the switch and . The voltage measured in CH2 by the voltage transformer; the proportion is 1 V = 100 V; in CH1, 1 V = 1 A; the time per DIV is 100 ns. In CH1, the voltage per DIV is 7.5 V; in CH2, the voltage per DIV is 7.5 V; the time per DIV is 16.6 us.
