Abstract
A parallel operating system for A.C. output converters of high frequency PWM inverters of an instantaneous current valve control type is provided with a current minor loop for controlling the instantaneous value of the output current. The current of each inverter minor loop is adapted to be supplied with a command value from a voltage major loop and a command value corresponding to the load current to be borne by each converter derived from the load current, as the command value for the current to be output by the converter for maintaining the output voltage at a sine wave.
