ABSTRACT:
A power conversion apparatus has a voltage type power convertor, a power control circuit for outputting a first active power reference signal for the voltage type power convertor based on a power reference value Pref and a detection value P of a power detector, a DC voltage detector for outputting a second active power reference signal for the voltage type power convertor based on a DC voltage reference value Vdref and a detection value Vd of the DC voltage detector, and a gate control circuit for firing switching elements in the voltage type power convertor based on both first and second active power reference signals.
