Inverter circuits are key technology for converting DC power to AC power and are widely used in fields such as photovoltaic power generation, UPS, motor drives, and welding equipment. Typical inverter circuits include DC-DC boost (required for some applications), full-bridge inverter, and output filtering. In applications, the focus needs to be on efficiency optimization, thermal management, and reliability. To this end, it is important to select low-loss devices with soft switching characteristics, optimize the switching frequency and drive circuit, and rationalize the thermal design.
