There are many kinds of inverters, which can be classified according to different methods.

1. According to the number of output phases of the inverter, it can be divided into single-phase inverter, three-phase inverter and multi-phase inverter.

2. According to the main circuit of the inverter, it can be divided into single end inverters, push-pull inverters, half bridge inverters and full bridge inverters.

3.According to the type of inverter's main switch devices, it can be divided into thyristor inverter, transistor inverter, field-effect inverter and insulated gate bipolar transistor (IGBT) inverter. It can also be classified into two categories: half controlled inverter and full control inverter.
4. According to the inverter output power to points, can be divided into active inverter and passive inverter.  The inverter output power transmission to the industrial power grid, called active inverter; where inverter output power output to the inverter with some electric load is called passive inverter.

5.According to the frequency of the AC power output of the inverter, it can be divided into the power frequency inverter, the intermediate frequency inverse and the high frequency inverter. Inverter with frequency is from 50 to 60Hz, the frequency of the intermediate frequency inverter is generally 400Hz to 10 kHz. The frequency of high frequency inverter is generally 10 kHz to MHz.
6.According to the waveform of the output voltage or current of the inverter, it can be divided into sine wave output inverter and non sinusoidal output inverter.
7.According to the operating mode of the inverter switch circuit, it can be divided into resonant inverter, fixed frequency hard switching inverter and fixed frequency soft switching inverter.

8.According to the DC power supply, it can be divided into voltage source inverter (VSI) and current source inverter (CSI). The former, the DC voltage is near constant, the output voltage is alternating square wave, the latter, the DC current is near constant, and the transmission current is the alternating square wave.
9. According to the waveform of the output voltage or current of the inverter, it can be divided into sine wave output inverter and non sinusoidal output inverter.

Modern inverter technology is a science and technology to study the theory and application of inverter circuit. Modern inverter technology is a science and technology research of inverter circuit theory and application. It is built in the industrial electronic technology, semiconductor device technology, modern control technology, modern power electronic technology, semiconductor converter technology, pulse width modulation (PWM) technology is a practical technology based on the subject.
