Abstract

PURPOSE:To control a voltage so as to obtain a desired voltage also through the fluctuation in a load current, by placing another transformer between the circuit in the side of output winding and the circuit in the side of winding for voltage detection of the transformer. CONSTITUTION:The output of commercial AC power supply 0 is subjected to full wave rectification and connected to terminals 7, 8 of the primary winding 9 of a switching transformer T1. This transformer T1 is provided with an output winding 10 and a winding for detecting a voltage 11, and further, a winding for feed back 12. Here a transformer T2 equipped with a winding 15 to be connected to a part where a half-wave pluse current flows in the circuit that is connected to the winding 10, and winding 16 to be connected to a part up to a smoothing condenser 14 in the circuit that is connected to the winding 11, is provided. Then, the tranformer T2 gives unidirectional induced voltage of an intensity proportional to the changed portion of the current for a unit time of the half-wave pulse current flowing in the winding 10 and required polarity to the circuit of the winding 11. Thereby voltage control is carried out also by a changed portion of the DC output voltage due to the fluctuation in the load current.
