<p>A rectifying and smoothing circuit (3) which includes a first inductor connected between one end (2b1) of an output winding of a transformer (2) and a low potential-side output portion (16b), a second inductor connected between the other end (2b2) of the output winding and the low potential-side output portion, a first rectifying element (11) connected between the one end of the output winding and a high potential-side output portion (16a), and a second rectifying element (12) 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 (17a) and a second winding (17) of a transformer, which are wound in a manner permitting magnetic fluxes generated by respective currents flowing therethrough to cancel each other. <IMAGE></p> |
