1. Working principle and characteristics: Working principle: The core of the inverter device is the inverter switch circuit, referred to as the inverter circuit. The circuit completes the inverter function by turning on and off the power electronic switch. Features: (1) High efficiency is required. Due to the high price of solar cells at present, in order to maximize the utilization of solar cells and improve the efficiency of the system, we must try to improve the efficiency of the inverter. (2) High reliability is required. At present, the photovoltaic power station system is mainly used in remote areas, and many power stations are unattended and maintained, which requires the inverter to have a reasonable circuit structure, […]
