N2 - Series-connected IGBTs, with their ability to withstand high voltages, are necessary to fully achieve High-Voltage DC (HVDC) Transmission and Flexible AC Transmission (FACT). In this paper, a hardware implementation method of a self-balancing control of series IGBTs is developed and tested. The proposed method does not rely on either resistive balancing components because of high power loss or costly high-end digital units. Instead, it regulates the voltage sharing among IGBTs via gate pulse delays introduced at modulation stage. Experiments with 4 series modules indicate that the proposed hardware implementation method is able to enhance both the steady-state and transient voltage sharing. The auxiliary balancing circuits consume low energy loss per cycle.
