How does thyristor realize DC-to-AC inverter? What is the principle?
Based on the principle of oscillator, DC power is first converted into pulse AC power with amplitude varying with time, and DC component is removed by DC isolation system, while AC component is retained. Then through the transformation system (boost or buck), the AC power supply that meets our needs is transformed, shaped and stabilized.

The inverter is composed of many parts, and the core part is the oscillator. The earliest oscillator was electromagnetic and later developed into electronic. From discrete components to application-specific integrated circuits to microcomputer control, it is becoming more and more perfect, and the function of inverter is getting stronger and stronger, which is widely used in various fields.
