Abstract

PURPOSE:To simplify a chopper control part by a method wherein a triangle wave is made by integrating the output voltage of a DC-AC inverter and is given to a voltage comparator together with output-terminal voltage and chopper control is performed by a pulse signal thereof. CONSTITUTION:DC voltage of an input terminal 1 is interrupted by a chopper 2, the AC voltage thereof is turned to DC voltage by a smoothing circuit 3 and given to the DC-AC inverter 4, and further is converted into DC by a smoothing circuit 5 and delivered. Moreover, the output of the inverter 4 is converted into the triangle wave by an integrating circuit 13, reference voltage 10 is overlapped thereon and the output thereof is given to the voltage comparator 12 together with the voltage of the output terminal 6, and there the conversion of a pulse width is performed in such a manner that the pulse width becomes small when the output voltage turns to be high and that it becomes large when the output voltage turns to be low. Accordingly, a pulse generator becomes unnecessary, thereby the chopper control part 14 is simplified, and thus the stabilization of the output voltage can be performed.
