High voltage frequency converter is a power regulation device used to control high-power motors. It can convert the 

fixed frequency and fixed voltage electrical energy output by AC power into adjustable frequency and adjustable voltage 

electrical energy to achieve precise control and speed regulation of the motor.

Common types of high-voltage inverters include the following:

1. Voltage type frequency converter: By adjusting the output voltage to achieve motor speed regulation, it is suitable for 

motor control under low power and low load conditions.

2. Frequency type frequency converter: By adjusting the output frequency to achieve motor speed regulation, it is suitable 

for motor control under high power and high load conditions.

3. Vector type frequency converter: By vector controlling the voltage and current of the motor, more precise speed and 

torque control can be achieved, which is suitable for motor control that requires high-speed response and operational 

stability.

High voltage frequency converters have the following characteristics:

1. Wide speed regulation range: High voltage frequency converters can achieve continuous speed regulation of motors, 

with a wide speed regulation range, meeting the precise control requirements under different loads and working 

conditions.

2. Low energy consumption: The high-voltage inverter adopts advanced power electronic technology and control 

algorithms, which can achieve efficient motor control and reduce system energy consumption.

3. Easy to operate: The high-voltage inverter has a friendly human-machine interface and rich communication interfaces, 

which can achieve remote monitoring and control, making it easy to operate and maintain.

4. High reliability: The high-voltage inverter adopts advanced protection and self diagnostic functions to ensure the safe 

and reliable operation of the equipment. At the same time, it can also achieve various protection functions such as grid 

connection and DC bus, enhancing the stability of the system.
