Abstract

PURPOSE:To contrive to drive a load normally, even when a battery voltage drops, by adding an auxiliary power to the power source of a separately excited control circuit. CONSTITUTION:A series path of the winding L1, diode D2 and current-limiting resistance RL of an oscillating transformer is connected in parallel with the power source, that is, a series path of the winding Ls and diode Ds of a separately excited control circuit 5. A voltage appearing at both ends of said winding L1 depends on the voltage of a winding Lc connected with the collector of an oscillating transistor Q1, and is not influence directly by the voltage of a battery to be charged 1. Therefore, when said voltage of the battery to be charged 1 and the both end voltage of the winding Ls drop, the power of said separately excited control circuit 5 is supplied supplementarily from the winding Lc and the source voltage of the separately excited control circuit 5 is stabilized accordingly so that the oscillation of a transistor inverter can be stabilized.
