Introduction To Solar Inverters

A solar AC power generation system consists of solar panels, a charge controller, an inverter, and a battery; a solar DC power generation system does not include an inverter. The process of converting AC power into DC power is called rectification, the circuit that performs the rectification function is called a rectifier circuit, and the device that implements the rectification process is called a rectifier or inverter. Conversely, the process of converting DC power into AC power is called inversion, the circuit that performs the inversion function is called an inverter circuit, and the device that implements the inversion process is called an inverter or inverter.

The core of an inverter device is the inverter switching circuit, or simply the inverter circuit. This circuit performs the inversion function by turning on and off power electronic switches. The switching on and off of power electronic switching devices requires certain drive pulses, which may be regulated by changing a voltage signal. The circuit that generates and regulates these pulses is usually called a control circuit or control loop. In addition to the inverter circuit and control circuit mentioned above, the basic structure of an inverter device also includes protection circuits, output circuits, input circuits, and output circuits.
