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 performs the rectification function is called a rectification circuit, and the device that implements the rectification process is called a rectification device or a 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 an inverter switching circuit, referred to as an inverter circuit for short. This circuit completes the inverter function by turning on and off the power electronic switch. The switching of power electronic switching devices requires certain driving pulses. These pulses may be adjusted by changing a voltage signal. The circuit that generates and regulates the pulse is often called a control circuit or control loop. The basic structure of the inverter device includes a protection circuit, an output circuit, an input circuit, an output circuit, etc. in addition to the inverter circuit and the control circuit described above.
