Abstract : The patent describes a transistorized chopper driver and feedback circuit apparatus having separate input and output grounds for providing a regulated D.C. to D.C. power converter apparatus. The chopper driver and feedback circuit uses a master square wave oscillator which has a transformer-coupled output to supply both polarities of the same output wave referenced to both grounds. A feedback circuit is used to drive the main chopper transistors with a feedback signal derived from the output voltage of the power converter.
