Inverters, also known as power regulators and power regulators, are an essential part of photovoltaic systems. The main function of the photovoltaic inverter is to convert the direct current generated by the solar panel into the alternating current used by household appliances. All the electricity generated by the solar panel must be processed by the inverter before it can be exported to the outside world. Through the full-bridge circuit, the SPWM processor is generally used for modulation, filtering, boosting, etc., to obtain sinusoidal AC power that matches the lighting load frequency and rated voltage for use by the end users of the system. With an inverter, DC batteries are used to provide AC power to appliances.
