Apparatus for adjusting winding of DC/DC converter and DC/DC converter with multi-output using thereof

摘要

PURPOSE: A DC/DC converter winding control device for obtaining multi-output and a multi-output DC/DC converter using the same are provided to obtain multi-output using a single transformer in a DC/DC converter. CONSTITUTION: A switching signal generating unit(336) generates a switching signal according to changes of the output voltage change of a DC/DC converter. A switching unit(334) controls the winding number of secondary winding by switching using a semiconductor switching element according to the switching signal. Induced voltage is applied to the secondary winding by the voltage applied to primary winding of the DC/DC converter.
