Abstract
Plural systems of switching signals are obtained from a single microprocessor for driving a plurality of motors and other apparatuses while achieving effective use of ports of the microprocessor. In principle, three kinds of switching signals based on three-phase are generated in the microprocessor, the three kind of switching signals are converted to six kinds of switching signals in circuits external to the microprocessor, and then the signals are supplied to their respective switching elements in an inverter circuit.
