Gate power supply circuit. |
摘要 |
<p>A gate power supply circuit including a switching device and a gate drive circuit connected to the switching device for generating a gate signal to be supplied to a gate of the switching device. The gate power supply circuit further includes a first series circuit of a first capacitor and an inductor, connected in parallel with the switching device, and a second series circuit of a first diode and a second capacitor, connected in parallel with the inductor. The gate drive circuit is connected to the second capacitor to receive energy stored in the second capacitor as power source for the gate drive circuit. <IMAGE></p> |
