Wireless control of load current sharing information for parallel-connected DC/DC power converters

An alternative means of communicating the load-sharing information among parallel-connected converters through the se of a wireless digital communication technique is presented. The idea is experimentally tested using two buck converters parallel-connected under the Master/Slave current-sharing (CS) configuration. The results show current distribution property of the converter system under the proposed wireless control scheme are similar to those obtained from a fixed-wire CS controller.
