Systems and Methods For Reducing Circulating Current and Phase to Phase Imbalance In A Parallel Modular Converter System

摘要

A system and method for providing power to a vehicle with reduced circulating current and phase-top-phase imbalance is disclosed. The system can include a plurality of parallel module converter for prioritizing and allocating each electrical load to one or more parallel modular converter modules. The system can also comprise a load balancer to ensure that differences in the properties (e.g., impedance) of the parallel modular converter modules do not create circulating currents or phase-to-phase imbalances. The load balancer can monitor the outputs to the plurality of parallel modular converter modules and modify the inputs to equalize, synchronize, or both the outputs.
