A boundary voltage mode control strategy is proposed in this study, which makes it able to achieve zero current switching (ZCS) for single-phase full-bridge current source inverter. The proposed control strategy can also effectively reduce the inductance required on the DC side. The basic principle of boundary voltage control and the conditions for achieving ZCS are analyzed. Based on the area equivalence principle, the reason for reducing inductance is analyzed through mathematical derivation. On the basis of theoretical analysis, simulations and experiments were conducted. The feasibility of the proposed critical voltage control strategy is verified by simulation and experimental results.
