Open-Loop Simulation of Single-Phase Full-Bridge Inverter with Integrated Z-Source and Boost Circuit

This paper presents a comprehensive methodology for conducting open-loop simulation of a single-phase full-bridge inverter that combines Z-source network with Boost converter circuitry. The implementation involves designing a specialized modulation scheme to control the shoot-through states unique to Z-source inverters while maintaining boost functionality. Key simulation components include parameter configuration for passive elements (inductors/capacitors), switching device modeling, and gate signal generation algorithms. The simulation workflow covers inverter design principles, circuit schematic development using power electronics simulation tools, and precise parameter initialization for both Z-network and Boost converter sections. Results analysis focuses on output voltage waveform quality, harmonic distortion metrics, and efficiency evaluation under various operating conditions. Through this study, engineers will master fundamental open-loop simulation techniques for hybrid Z-source/Boot converters, establishing critical foundations for subsequent closed-loop control implementation and system optimization. The simulation approach utilizes state-space modeling techniques to represent the unique impedance network behavior during both shoot-through and non-shoot-through operating states.
