Inverter is the brain and heart of the photovoltaic power generation system in the process of solar photovoltaic power generation, photovoltaic array, by the power to direct current (dc) can, however, many load for ac power dc power supply system has great limitation, not easy to transform voltage, load application scope is limited, in addition to the special load, all you need to use the inverter dc transform into alternating current The photovoltaic inverter is the heart of the solar photovoltaic power generation system. It converts the direct current generated by photovoltaic modules into alternating current, which is transmitted to the local load or power grid. The photovoltaic inverter is mainly composed of the power module to control the circuit board, circuit breaker, filter, reactor and transformer The contactor and the cabinet and other components, the production process includes electronic parts pre-processing, complete machine assembly and testing, complete machine packaging and other process links, its development depends on the development of power electronics technology semiconductor device technology and modern control technology Link: https://www.zhihu.com/question/360368108/answer/1491117442 source: zhihu copyright all business reprint, please contact the author or authors obtain authorization, non-commercial reprint please indicate the source
