2HP/1.5kW VFD

Single phase VFD drive normally is used in 200V AC to 240V AC in low power applications, like small pumps. The AC motor's input need to be three phase as all of the drives are three phase output. In our factory, the 1 phase AC drives, from 0.4kW to 2.2kW.

A VFD consists of a rectifier/filter section which converts the incoming AC to DC. This high-voltage DC is then converted back to AC with additional controls which provide the speed control. The problem with single-phase AC power is at the input side of the VFD, the part that converts incoming power to DC. When you rectify a three-phase power source, the output voltage from the rectifier never drops below 50% of the peak voltage. This makes it real easy to filter and provide pure DC to the rest of the equipment.

Variable Frequency Drive (VFD) can be used to control the speed of three-phase induction motor. A variable frequency drive is a system equipped for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.

The major source of problems in the real world is conducted emissions and these are typically in the region of 20kHz to 10MHz. The source of the emissions is the output of the VFD which comprises 6 solid state switches that switch each output between the DC bus rails. These switches are typically high speed IGBTs which can switch in less than 100nS.
The output waveform is a PWM waveform designed to create a sinusoidal current flow into the motor
