Abstract

PURPOSE:To obtain multioutputs of a DC/DC converter with less number of components by inserting a choke coil to the primary side of a transformer. CONSTITUTION:When a transistor Tr1' is conducted ON, a current ITR1' flows, and power is supplied through a transformer T1' to loads R1'-T3'. Simultaneously, energy is stored in a choke coil, and is supplied only to a load R1' through a diode D2 when the transistor TR1' is interrupted OFF. Currents ID1- ID4 flowing through diodes D1-D4 are smoothed via capacitors C1-C3. The load voltages V01'-V03' are respectively fed back through controllers CONT1'- CONT3', and are stabilized by varying the ON times of the transistors TR1'- TR3'. In this manner, a multioutput DC/DC converter can be obtained with one choke coil L1'.
