Abstract
A rectifying and smoothing circuit (,) which includes a first inductor connected between one end (,) of an output winding of a transformer (,) and a low potential-side output portion (,), a second inductor connected between the other end (,) of the output winding and the low potential-side output portion, a first rectifying element (,) connected between the one end of the output winding and a high potential-side output portion (,), and a second rectifying element (,) connected between the other end of the output winding and the high potential-side output portion, and which generates a DC voltage (V0) by rectifying and smoothing a bipolar voltage (VS) induced across the output winding, has a construction permitting reduction of the size and manufacturing costs thereof and enhancement of smoothing effects. In this rectifying and smoothing circuit, the first and second inductors are constructed by a first winding (,) and a second winding (,) of a transformer, which are wound in a manner permitting magnetic fluxes generated by respective currents flowing therethrough to cancel each other.
