Description of Operation:
The frequency converter supplies a regulated amount of mains AC power to a standard 3 phase induction motor to control the motor speed. The frequency converter supplies variable frequency and voltage to the motor.
The frequency converter is divided into four main modules.
- Rectifier
- Intermediate circuit
- Inverter
- Control and regulation

Control Principle:
A frequency converter rectifies AC voltage from mains into DC voltage, after which this DC voltage is converted into a AC current with variable amplitude and frequency. The motor is supplied with variable voltage/current and frequency, which enables variable speed control of 3-phased, standard asynchronous motors and permanent magnet motors
