Modern DC/AC inverter technology is a static converter technology that uses power semiconductor devices to convert direct current energy into alternating current energy. Inversion technology has broad application prospects in the field of solar photovoltaic power generation. This book comprehensively and systematically elaborates on the application and development of photovoltaic inverters both domestically and internationally, including the basic knowledge of photovoltaic inverters, the application of soft switching technology in inverters, three-phase inverters, multi-level inverters, photovoltaic inverter design, inverter parallel technology, and photovoltaic inverter engineering applications. This book has novel themes, rich content, simple and easy to understand language, and has high practical value.
