Title: Switching power supply unit and operating method therefor
Inventor: SEKIGUCHI KIYOSHI
IPC: H02M3/28
Filed: 2000-04-11
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply unit and an operating method therefor wherein power loss resulting from overcurrent detection can be reduced to enhance the efficiency. SOLUTION: A latch circuit 7 is connected between the gate and source of a switching element Q1, and a frequency detection circuit 8 formed between the control winding T1c of a transformer T1 and the element Q1 is also connected with an oscillation control circuit 3 and the latch circuit 7. A frequency selection circuit 12 attenuates signals of higher frequencies than a cut-off frequency and meanwhile lets through signals of lower frequencies than the cut-off frequency. These signals of lower frequencies are converted into direct-current-like voltage signals through a second rectifying and smoothing circuit 13, and the output of the rectifying and smoothing circuit 13 is compared with a reference voltage V1 at a voltage comparison circuit 14.  If the result of the comparison reveals that the output of the rectifying and smoothing circuit 13 is higher than the reference voltage V1, a signal is outputted to the latch circuit 7 to actuate the latch circuit 7, which stops the oscillating operation of the switching element Q1. Thus, the phenomenon that the oscillation frequency is low when the output current is high is utilized to provide overcurrent protection.
