The variable-frequency driver is a device that converts AC with fixed voltage and frequency to AC with variable voltage and frequency; it is usually used to control the rotation speed or output torque of AC motors. Since the device that generates variable voltage and current in the variable-frequency driver is the “inverter”, therefore the variable-frequency driver is usually also called “inverter”.
Variable-frequency driver composition: It includes the inverter board and panel.
