Abstract

PURPOSE:To increase the efficiency of a method of controlling an inverter by calculating the number of pulses corresponding to the ON-OFF time of the output voltage waveform by a microprocessor from the difference between a set rotating speed and the rotating speed of a motor and producing a switching control signal on the basis of the number of pulses. CONSTITUTION:The stored content of an ROM9 which stores the number of pulses for determining the maximum efficiency operation frequency unitarily determined by the set rotating signal is inputted to a microprocessor 8. The microprocessor 8 calculates the number of pulses corresponding to the ON-OFF time duration of the output voltage waveform from the difference between the set rotating speed and the rotating speed of a motor 2, outputs the result to a pulse counter 11, and outputs a switching signal to a gate circuit 13 at every completion of counting by the counter 11.
