Abstract

PURPOSE:To always maintain the ratio of the output voltage of an inverter to a set frequency constant by varying a set address signal to an ROM which stores a control signal of a switching element in response to the variation in the voltage of a 3-phase AC power source. CONSTITUTION:Variations in the voltages of 3-phase AC power source are detected, and the detected voltages are converted via an A/D converter into a binary coded S8. On the other hand, a multiplying circuit 21 which produces a product of a binary coded signal S4 from a speed setting circuit 20 and a binary coded signal S6 representing a reference voltage between terminals S and N, and a dividing circuit 25 which divides a binary coded signal S7 outputted from the circuit 21 by a binary coded signal S9 outputted from an A/D converter 26 are provided, thereby varying a set address signal to an ROM 28 in response to the variation in the voltage of a 3-phase AC power source. The output signal S12 of the ROM 28 is applied through a waveform synthesizer 29 and an inverter circuit 30 to the switching element of the inverter.
