Abstract

This paper proposes estimation method of optimized switching points for on-off module control to improve overall power conversion efficiency of paralleled converter system. On-off module control changes the number of active modules according to load current. The main concern of the control is to determine the on-off points of converter modules. Optimized switching points for on-off control are estimated by simple manner. Experimental results show the effectiveness of proposed estimating method to improve the efficiency.
