Definition of Solar Inverter

2022-11-15

Inverter, also known as power regulator, power regulator, is an indispensable part of photovoltaic system. 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. Through the full-bridge circuit, the SPWM processor is generally used to modulate, filter, boost, etc., to obtain a sinusoidal AC power that matches the lighting load frequency, rated voltage, etc. for the end user of the system. With an inverter, a DC battery can be used to supply AC power to the appliance.
The solar AC power generation system is composed of solar panels, charge controllers, inverters and batteries; the solar DC power generation system does not include inverters. The process of converting AC power into DC power is called rectification, the circuit that completes the rectification function is called a rectifier circuit, and the device that realizes the rectification process is called a rectifier device or rectifier. Correspondingly, the process of converting DC power into AC power is called inverter, the circuit that completes the inverter function is called inverter circuit, and the device that realizes the inverter process is called inverter equipment or inverter.

The core of the inverter device is the inverter switch circuit, which is referred to as the inverter circuit for short. The circuit completes the inverter function by turning on and off the power electronic switch. The on-off of power electronic switching devices requires certain driving pulses, and these pulses may be adjusted by changing a voltage signal. The circuits that generate and condition the pulses are often referred to as control circuits or control loops. In addition to the above-mentioned inverter circuit and control circuit, the basic structure of the inverter device also includes a protection circuit, an output circuit, an input circuit, and an output circuit.
