1. Inverter circuit

The reverse process corresponding to rectification is called inversion (DC to alternating current). If the AC side of the converter is connected to the AC power supply, the DC inverse becomes the same frequency alternating current feedback to the power grid, it is called active inverter; if the AC side of the converter is connected to the load, the DC inverse becomes the alternating current supply load of a frequency or variable frequency, which is called passive inversion.

2. Active inverter circuit

Working principle

3. Passive inverter circuit

Single-phase voltage-type inverter circuit

Three-phase voltage-type inverter circuit (can be regarded as a three half-bridge inverter circuit composition)

Current-mode inverter circuit

4. PWM Control Technology

Fundamentals (Impulse Equivalence Principle) (area equivalence principle)
