Abstract :
A new topology bi-directional Z-source inverter is proposed. It can overcome the uncontrollable and unstable limitations of the Z-source inverter in DCM mode. The operational principle, design guidelines of Z-source networks and power devices are provided. A DC clamp snubber circuit is developed to limit the voltage spike on power device. Power loss analysis and 3-D design for Z-source inverter system are presented. A prototype of 55 kVA bi-directional Z-source inverter is designed to verify the principle and performance of the proposed topology.
