Abstract :
Applications with paralleled or interleaved 3-phase converters are reviewed and the issues related to circulating currents between modules sharing the same DC bus and the same load are discussed. A new methodology based on special synchronization of the PWM zero-sequence states is introduced and its effect on different applications is analyzed and simulated. An example of a DSP implementation is shown
