MULTI-OUTPUT CURRENT-RESONANT TYPE DC-DC CONVERTER
摘要
<p>A multi-output current-resonant type DC-DC converter comprises an output controlling MOS-FET (40) connected between a second secondary winding (5c) of a transformer (5) and a second output smoothing capacitor (16) of a second rectification smoothing circuit (17), and an output control circuit (41) for controlling the ON/OFF of an output controlling MOS-FET (40) on the basis of the voltage V<SUB>02</SUB> of the second output smoothing capacitor (16). By turning ON/OFF the output controlling MOS-FET (40) in synchronism with the switching frequency of a first or second main MOS-FET (1, 2), it is made possible to achieve an ideal cross regulation with each DC output and to achieve a highly stable DC output with a little power conversion loss and with a simple circuit change. The multi-output current-resonant type DC-DC converter realized is inexpensive but high in the power conversion efficiency, and can have a highly precise DC output.</p>
