Title: Switching power circuit
Inventor: AZUMA KAZUYUKI
IPC: H02M1/08
Filed: 2001-08-06
Abstract: PROBLEM TO BE SOLVED: To provide a switching power circuit for supplying power to a drive circuit of a power semiconductor element, capable of preventing lowering of output voltage generated in driving the power semiconductor element. SOLUTION: A load control device 104 outputs a PWM drive signal to a drive circuit 102 for driving IGBTQ1. An edge detector circuit 112 detects the falling edge of the PWM drive signal, to generate a pulse signal which is synchronized with the PQM drive signal. The pulse signal permits current to run through a transformer 115, to generate drive power on its secondary side. The drive power permits charging current to run through a voltage-smoothing capacitor C and to conduct discharging and charging for turning on the IGBTQ1. Thus, lowering of output voltage can be prevented, by discharging the voltage smoothing capacitor C. Consequently, use of the voltage-smoothing capacitor of large volume type can be eliminated, which was required, to prevent the lowering of output electric power.
