What's the different between vvvf and soft starter?

VVVF and soft starter are two different types of motor control systems that serve different purposes:

1. VVVF (Variable Voltage Variable Frequency) is a method of controlling the speed of an AC motor by adjusting both the voltage and frequency of the power supply. This type of control is achieved by using an electronic inverter to vary the output voltage and frequency in response to the required speed of the motor. VVVF is commonly used in applications where precise speed control is required, such as in elevators, cranes, and industrial machinery.

2. Soft starter, on the other hand, is a device used to control the starting current of an AC motor by gradually increasing the voltage applied to the motor during start-up. The soft starter typically uses solid-state devices such as thyristors or triacs to control the voltage applied to the motor. The purpose of a soft starter is to reduce the inrush current that occurs during motor start-up, which can cause damage to the motor windings and other components. Soft starters are commonly used in applications where starting torque is not critical, such as in conveyor belts, pumps, and fans.

In summary, VVVF is used for precise speed control of AC motors, while soft starters are used to reduce the inrush current during motor start-up.
