How to control the circuit of On-Grid Solar Inverter？

We all know that the main circuit of the On-Grid Solar Inverter needs to be realized by a control circuit. Generally, there are two control methods of square wave and sine wave. The square wave output inverter power circuit of the On-Grid Solar Inverter is simple and cost-effective. Low, but low efficiency, large harmonic components. The sine wave output of On-Grid Solar Inverters is the development trend of inverters. With the development of microelectronics technology, microprocessors with PWM functions have also come out. Therefore, the sine wave output of On-Grid Solar Inverters is inverse The changing technology has matured. So how should we On-Grid Solar Inverters and how to control the circuit? Let's take a look together next. Let us know more about the circuit control of On-Grid Solar Inverters.

On-Grid Solar Inverter with square wave output

On-Grid Solar Inverters with square wave output mostly use pulse width modulation integrated circuits. The practice has proved that the circuit of On-Grid Solar Inverters is integrated using square wave output, and the On-Grid Solar Inverters with square wave output use power as a switching power element, the field-effect tube can realize an On-Grid Solar Inverter with relatively high performance and price. It can to directly drive the power field effect tube and has an internal reference source, operational amplifier, and Undervoltage protection. Therefore, the On-Grid Solar Inverter the peripheral circuit of the converter is very simple.

The sine wave output On-Grid Solar Inverter control integrated circuit, the sine wave output On-Grid Solar Inverter, the sine wave output On-Grid Solar Inverter control circuit can be controlled by a microprocessor, and these single-chip microcomputers have multiple channels The PWM generator can set the dead time between the upper and lower bridge arms, realize the sine wave output circuit, complete the generation of the sine wave signal, and detect the AC output voltage to achieve voltage stabilization. The output end of the On-Grid Solar Inverter circuit with sine wave output generally uses an LC circuit to filter out high-frequency waves to obtain a pure sine wave.
