Solar inverters, also known as power regulators and power regulators, are an indispensable 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 home appliances. All the electricity generated by the solar panel must be processed by the inverter before it can be output externally. Through the full-bridge circuit, the SPWM processor is generally used for modulation, filtering, boosting, etc., to obtain a sinusoidal AC power that matches the lighting load frequency and rated voltage for use by the system end users. With the inverter, DC storage batteries can be used to provide AC power to electrical appliances.
