摘要
太阳能是绿色无污染的清洁能源,在光伏发电领域有着重要的应用价值。系统所设计的UPS光伏逆变器采用了内置高频变压器的两级模式,通过前级DC/DC高频升压,后级DC/AC工频逆变的模式,实现了12 VDC到220 VAC的电能转换。该设计模式具有电路简单、性能稳定、电能转换效率高等特点。
Solar energy is green pollution-free clean energy and has important application value in the field of photovoltaic power generation. Photovoltaic inverter UPS system that adopted two built-in high-frequency transformer models had been achieved a 12 VDC to 220 VAC power conversion through pre-DC / DC high frequency boost and post-DC / AC power frequency inverter model. This design pattern had some advantages such as simple circuit, stable performance, high energy conversion efficiency, etc.
