Abstract
PURPOSE:To ensure a stable operation of an AC generator by a method wherein the voltage/frequency ratio is ket constant by a frequency controlling circuit provided with a delay circuit generating a delay equivalent in time length to the delay created in an inverter output voltage controlling circuit. CONSTITUTION:The voltage and frequency of power from an AC source 1 are prescribedly converted in a converter 2 and an inverter 4 and then supplied to a motor 5. The output voltage is regulated in a lineup of a voltage controlling circuit 13, a current controlling circuit 15, and a phase controlling circuit 16 in response to a signal supplied by a setter 10 through an input controlling circuit 11 while the output frequency is regulated in a lineup of an oscillator 17, a ring counter 18, and a pulse amplifying circuit 19. The voltage regulating lineup inclides some factor causing a time delay while the frequency regulating lineup none. A delay circuit 20 is therefore inserted in the latter lineup realizing a delay equivalent in time length to the one in the former lineup.
