IPC: H02M1/06
Filed: 1989-08-28
Abstract: PURPOSE:To reduce gate driving power by setting an estimated time till the joint temperature of a thyristor comes to a fixed value or higher after a power converter starts working, and by reducing the scale of the ON-gate current of the thyristor after said set time. CONSTITUTION:Within the set time of a timer circuit 7, a semiconductor switch 6 is closed, and output from both ON-gate circuits 2, 3 connected to each other in parallel is set to be output current from the gate terminal G of a gate driving circuit 1.
