The 12v inverter, also known as the inverter power supply, is a power conversion device that can convert 12V or 24V direct current into 240V, 50Hz AC or other types of AC. Its output AC power can be used for all kinds of equipment, to maximize the needs of users in mobile power supply places or areas without electricity for AC power. With the inverter, it can be used to convert direct current (battery, switching power supply, fuel cell, etc.) into alternating current to provide stable and reliable power protection for electrical appliances, such as notebook computers, mobile phones, handheld PCS, digital cameras and various instruments; The inverter can also be used with the generator, which can effectively save fuel and reduce noise; In the field of wind and solar energy, inverters are essential. Small inverters can also use cars, ships, and portable power supply equipment to provide AC power in the field.

Classification and characteristics of inverters

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

1. According to the frequency of the inverter output AC power, it can be divided into power frequency inverter, medium frequency inverter and high frequency inverter.

2, according to the inverter output phase points, can be divided into single-phase inverter, three-phase inverter and polyphase inverter.

3, according to the direction of the inverter output power, can be divided into active inverters and passive inverters.

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

5, according to the type of inverter main switching device, it can be divided into thyristor inverter, transistor inverter, field effect inverter and insulated gate bipolar transistor (IGBT) inverter.

6, according to the DC power supply, it can be divided into voltage source inverter (VSI) and current source inverter (CSI).

7, according to the inverter output voltage or current waveform, can be divided into sine wave output inverter and non-sine wave output inverter.

8, according to the inverter control mode, can be divided into frequency modulation (PFM) inverter and pulse width modulation (PWM) inverter.

9, according to the inverter switching circuit working mode, can be divided into resonant inverter, fixed frequency hard switching inverter and fixed frequency soft switching inverter.

10, according to the inverter commutation mode, can be divided into load commutation inverter and self-commutation inverter.

The main features of the inverter are:
