Original Abstract

Voltage power supply is a part of every electric device. Mostly input voltage of each part of device has to be adjusted. Adjustment means increase or decrease of output voltage, use of rectifier, filtration and stabilization. Switching changers are more applied thanks to their features such as efficiency, weight and dimensions. Thanks to high quality regulation circuits are switched changers used as laboratory power supplies. But they are only used as supplies of one constant voltage. If only one output voltage is used there is a possibility of adaptation of control circuits for regulation of one variable output voltage. There is a problem with need of more than one variable output voltage. On principle there isn’t a possibility of control of changer using more than one feedback. This thesis deals with construction of switching changer with more than one variable output voltage. The goal is in use of independent secondary pulse-width regulation. Changer than works as a regulator of constant secondary voltages and regulation of output voltage is made by secondary switching regulator which is synchronized with primary exciting circuitry.
