"Wireless" control of spatially distributed power electronics

We propose a wireless control technique for spatially distributed power electronic systems and demonstrate its applicability for master-slave control of two parallel converters, namely a two-module parallel buck converter and a two-module parallel single-phase voltage source inverter. This scheme uses radiofrequency based communication to eliminate the need for multiple physical connections among the various modules of the parallel converters and is expected to lead to simpler and redundant design of distributed power systems that is achievable using the droop method, while maintaining load sharing among the various modules. The proposed method can also be used as a backup for wire-based control of parallel converters, in applications where fault tolerance is of critical importance.
