ABSTRACT:
A switching regulator includes: a boost chopper circuit A including a plurality of inductances 2, 3, 4 and 5 which are connected in parallel with a D.C. power supply 1 for boosting the D.C. power supply 1, a plurality of commutating diodes 6, 7, 8 and 9 which are connected to output sides of those inductances 2, 3, 4 and 5, respectively, a plurality of switching elements 10, 11, 12 and 13 for connecting the D.C. power supply 1 and nodes between the respective inductances 2 to 5 and the respective diodes 6 to 9 in a short-circuiting manner, and a smoothing capacitor 14 connected in series to a combined output section of those diodes 6 to 9; a control circuit 15 for controlling the on/off operation of those switching elements 10 to 13; and a load 16 connected in parallel with the smoothing capacitor 14. The plurality of switching elements 10 to 13 repeatedly operate while the operation of the plurality of switching elements 10 to 13 is sequentially delayed by a predetermined period of time.
