Abstract
A power conversion system that has two power conversion apparatuses each including a converter that can control a DC voltage and an inverter and that drives the AC motor by connecting the outputs of the two inverters in parallel is provided. The output voltage of one of the converters is controlled according to the difference between the detection currents detected by the two current detectors for detecting the output currents of the two inverters so that a cross current flowing through the two inverters is suppressed.
