Abstract :
This paper proposes a novel single-phase Buck-Boost Z-source inverter topology. This topology performs the Buck-Boost conversion and inversion ability in single stage by using the unique feature of the Z-source network. Compared to traditional two stage realization, it is simple in structure and only utilizes three switches to get the required output voltage lower or higher than input, in addition, the input current keeps continuous. Operating principle and switching modes are investigated in detail. One-cycle control strategy is developed to get the desired output. Simulations results will be presented to demonstrate the unique feature of proposed topology and the control strategy.
