Abstract
PURPOSE: To provide a power source wherein the secondary circuit of the power transformer is free from damage due to the extraordinary increase of its output current by controlling the power transformer so that its primary current may decrease when the overcurrent protecting circuit is put in operation.
CONSTITUTION: The output of an inversion circuit 18 is smoothed and superposed to the DC voltage of a condenser 15. When an overcurrent protecting circuit is put in operation smaller current is flowed into transistors 4a, 4b which have been control led than they are at an ordinary condition. In this way, since the current on the input part of a power transformer 6 is controlled so that it may decrease the output voltage is restrained.
