Title: Driving power supply for semiconductor switching element
Inventor: TABATA TAKEAKI
IPC: H02M1/08
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to supply electric power stably to the driving circuit of switching elements whatever state the switching elements are in. SOLUTION: Switching elements (insulated-gate bipolar transistors (IGBT)) Q1, Q2 are connected in series between a DC power supply Ed. When they are driven via gate driving circuits GDU1, GDU2 by using only a diode D1 and capacitors C1, C3, electric power cannot be supplied to GDU1 in a conventional art unless Q2 is turned on. This driving power supply circuit makes it possible to charge the capacitor C3 irrespective of the state of Q1, Q2, and to supply electric power to GDU1, by providing components including transistor T1, T2 and an oscillating circuit OCS and by turning on and off T1, T2 alternately.
