Cascaded Simulation of DAB Full-Bridge DC-DC Converter and Three-Phase PWM Converter

Cascaded simulation of DAB full-bridge DC-DC converter and three-phase PWM converter finds applications in charge-discharge systems and new energy fields, enabling bidirectional energy flow. Specifically, converters are electronic circuits that transform one form of voltage or current into another, typically achieved through transformer-based implementations. In the described charge-discharge system, the converter can transform battery DC power into AC power for grid injection, or conversely convert grid AC power to DC for battery storage when needed. For new energy applications, converters transform solar panel-generated DC power into AC for grid integration, or convert wind turbine-generated AC power into DC for battery storage and subsequent utilization. The simulation typically implements dual-active-bridge (DAB) control using phase-shift modulation algorithms for soft-switching operation, while the three-phase PWM converter employs space vector modulation techniques for optimal voltage utilization and harmonic reduction. Therefore, research on cascaded DAB full-bridge DC-DC and three-phase PWM converter simulations holds significant importance for advancing charge-discharge systems and new energy sector development.
