  • Control method for PWM converter
    Patent number: 4984147
    Abstract: In the control method for a PWM converter according to the present invention, an upper limit value of an inphase component of an instruction voltage for controlling an AC/DC converter is prescribed, and in the region where the upper limit value is exceeded, the inphase component of the instruction voltage is controlled to be within the prescribed upper limit value by setting a reactive component value corresponding to the exceeding quantity. This makes it possible to offer a low priced, stable control method for a PWM converter.
