A current-source inverter (CSI) possesses several advantageous features, including stable output current, a wide load range and immunity to current surges during load open-circuit conditions. In applications where reliability is critical, CSIs outperform voltage-source inverters (VSIs). However, traditional CSIs suffer from significant current droop during continuous discharge and the risk of overvoltage at the inductor terminals when the load is open-circuited, limiting their practical utility. To address these limitations, the relative positions of the inductor, switches and diodes within conventional CSIs are modified, so as to enable energy replenishment during continuous discharge. Meanwhile, a continuous current path through the inductor is ensured to effectively prevent overvoltage across the inductor terminals. A detailed theoretical analysis of the proposed circuit is conducted, and it is verified by simulations. Finally, an experimental prototype was designed to further validate the feasibility of this circuit.
