1. If the impact on the power grid can be reduced, it will not cause the problem of excessive peak-to-valley difference.
2. It can speed up the controllable function, so as to speed up the smoothing according to the needs of users;
3. The motor and equipment suspension method is controllable, so that the whole equipment and system are more safe, and the life expectancy will be increased accordingly;
4. Control the starting current of the motor, fully reduce the starting current, and reduce the maintenance cost of the motor;
5. It can reduce the wear and tear of mechanical transmission parts, thereby reducing the acquisition cost and improving the stability of the system.
6. The starting current of the motor is reduced, and the variable voltage and frequency are more reliable.
7. Effectively reduce the reactive power loss and increase the active power of the power grid
8. Optimize the process process, and can change quickly according to the process process, and can also achieve speed change through remote control PLC or other controllers

Introduction of four-quadrant regulator - Delixi
A four-quadrant power supply is a power supply capable of absorbing and supplying positive and negative currents and voltages. While a simple voltage converter is capable of generating a fixed output voltage from the input voltage, this feature is not sufficient in some applications. An example is the control of voltage nodes connected to capacitors that ...
