A soft-switching circuit for three-phase converter with unity power factor is proposed in this paper. A discontinuous conduction mode converter eliminates the complicated circuit control requirement, reduces a number of components, and reduces the filter reactive components size. In the discontinuous mode converter, the device must be switched off at a maximum inductor current. To achieve the zero voltage switching, the proposed converter is constructed by using a new resonant network in parallel with the switch of the conventional PWM converter. Soft-switched operation of the proposed PWM converter is verified by digital simulation and experimental results. A new PWM converter achieves the soft-switching for all switching devices without increasing their voltage and current stresses.
