What are the advantages of single-phase 220v to three-phase 380v inverter?

The general-purpose inverter is a power control device that controls the AC motor by changing the frequency of the working power supply of the motor, and converts the power frequency AC with a fixed voltage and frequency into a variable voltage or frequency. The working process of the AC device is to first convert the power frequency AC power into a DC power supply through a rectifier, and then convert the DC power supply into an AC power supply with controllable frequency and voltage to supply the motor.

The single-phase 220v to three-phase 380v inverter is based on the ordinary inverter, which converts the power frequency AC 220V power supply into a DC power supply through a rectifier, and then converts the DC power supply into a three-phase 380V AC power supply with controllable frequency and voltage. supply the motor. This method does not boost the voltage through a transformer, but only through a rectifier booster circuit, which greatly reduces the volume and weight of the inverter, and the cost is also low.

Use features

1. Ordinary civil electricity input, output fully matched with three-phase asynchronous motor;

2. It is billed according to civil single-phase electricity, which is economical;

3. The input wide voltage range is designed to adapt to the working environment where the mains voltage is generally low in some areas;

4. The output protection function is perfect, there are various protections such as overvoltage, overload, overtemperature, short circuit and overcurrent;

5. Some equipment can cooperate with sensors and PLC to achieve automatic control and energy saving purposes, such as temperature-controlled fans, water pumps and constant pressure water supply.

Real-world problems that can be solved

1. The power supply voltage does not match the problem, that is, the power supply is 220V, and the equipment power consumption is 380V;

2. The power supply phase does not match the problem, that is, the power supply is single-phase, and the equipment uses three-phase power;

3. The power supply frequency does not match the problem, that is, the power supply is 50Hz/60Hz, and the equipment power consumption is 0-650Hz (arbitrary setting).
