ABSTRACT:
An AC converter changes the frequency of an incoming voltage waveform to operate an induction motor driving a ventilation system at one or several different speeds. A program followed by a microprocessor utilizes the phase-to-phase incoming voltage waveform in a step-by-step sequence to generate control signals for the switches in a switching matrix. A full-speed subroutine, a three-quarter speed subroutine and a half-speed subroutine are disclosed for the microprocessor.
