Abstract

In this paper, an AC small-signal equivalent circuit model of continuous conduction mode (CCM) ZSI based on state space averaging is presented. The AC small-signal model includes the dynamics of ZSI introduced by the inductors and capacitors contained in the ZSI circuit, providing guidelines to the system control design. In addition, a novel modified space vector PWM is presented to distribute the shoot-through states into the zero vectors without compromise to the active space vector. Simulation results based on the design are presented, using the proposed SVPWM control strategy
