IPC: H02M3/28
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a switching power circuit which allows switching loss to be further reduced under light load. SOLUTION: This switching power circuit is designed such that under steady- state load, the voltage of a connecting point 10 is higher than a threshold and the voltage of a connecting point 7 is lower than the threshold, because of feedback from an output detection circuit 20. Therefore, during an oscillation frequency quiescent period, circuit 11 does not operate and an oscillation circuit 13 continuously outputs triangular waves. Under light load, the voltage of the connecting point 10 is lower than the threshold, and the voltage of the connecting point 7 is higher than the threshold because of feedback from the output detection circuit 20. Therefore, the oscillation frequency quiescent period circuit 11 is actuated, and the oscillation circuit 13 outputs triangular waves provided with the quiescent period of oscillation.  As a result, a switching element Q1 performs a switching operation such that it remains out of operation in an interrupted state for a certain period of time.
