ABSTRACT:
A rectifier control system with rectifiers connected in parallel operates constantly by ensuring balance between the rectifiers with respect to output voltage and current. The rectifiers apply a DC voltage to a single DC bus. Current detectors associated with the rectifiers detect the bus current flowing through the DC bus. Voltage control circuits associated with the rectifiers control the DC voltage to coincide with a voltage command value. Command value generating circuits associated with the rectifiers correct the voltage command value with a signal proportional to the detected bus current or a signal obtained by integrating or amplifying the bus current with an amplifier having a first order lag characteristic.
