Abstract
After an AC voltage was rectified and smoothed, it is stepped up by a chopper circuit. Another winding is magnetically coupled to a choke coil of the chopper circuit so as to have the same polarity. An inductance for adjusting a current is connected serially with another winding. A current of a phase opposite to a phase of a current flowing in the choke coil is generated in another winding, thereby setting off a ripple current flowing in an input smoothing capacitor.
