Abstract

PURPOSE:To contrive to miniaturize and to reduce the weight of the control circuit for the pulse width modulation type inverter by a method wherein a microcomputor containing an oscillator, a memory circuit and a microprocessor, and to output high frequency pulses for the formation of triangular waves and also digital quantities for the formation of the basic sinusoidal waves, etc., is provided. CONSTITUTION:The microcomputor 6 is constituted of the oscillator 13, the memory circuit 14 to store the digital quantities corresponding to the frequency, the voltage value and interrupting times, etc., of a call signal voltage, and the micorprocessor 15, etc. A triangular wave generator 7 is consisted of a frequency divider 16 and an integration circuit 17, and divides the frequency of pulses sent from the microcomputor 6 to convert into triangular waves. A sinusoidal wave generator 8 is consisted of a digital-analog converter 18 and a polarity conversion circuit 19. The high frequency triangular wave and the reference sinusoidal wave are compared in a comparator 9 to output a driving signal of pulse width modulation type. A detector 11 compares the DC voltage outputted from a rectification circuit 10 for automatic voltage regulation and the reference DC voltage to perform the voltage control.
