ABSTRACT:
A new method and apparatus for controlling the conversion of AC electrical energy into DC electrical energy. A microprocessor control system is operatively connected to an AC source and to a motor/regenerative switching bridge network. A control signal is operatively coupled to the microprocessor to selectively adjust the DC output voltage. The microprocessor monitors the control voltage, calculates the timing of gating signals and generates gating pulses to the bridge networks. The microprocessor also senses the phase rotation and the line frequency of the AC source and factors those parameters into account when determining gate pulse output pattern and timing.
