Abstract

A control method and apparatus to reduce current through a DC capacitor linking two converters causes the value of the DC-side current output of the first converter to approach the value of the DC-side input current into the second converter, thus minimizing the DC capacitor current which is equal to the difference between the output current from the first converter and the input current into the second converter.
