Abstract
A step-up/step-down pulse width modulated chopper circuit using power transistors is provided which allows the output voltage to be both decreased from its input value and increased from its input value and thereby made to follow a commanded prescribed reference waveform. A plurality of step-up/step-down choppers can be interconnected to provide single phase and multiphase ac outputs.
