<p>A primary-side power converter circuit employs a half bridge system and a synchronous rectifier circuit is used as a rectifier circuit of a secondary-side power converter circuit, whereby an on time ratio of the on time of a first switching element to the on time of a second switching element is controlled so as to provide an operation mode in which energy is regenerated from the secondary side to the primary side when the load is light,</p> |
