List of Inverter / VFD suppliers in Bangladesh

More information on Inverter / VFD

Variable Frequency Drive, shortly called as VFD is a widespread device in industrial purpose. The device may also be called as Inverter, VSD, Motor Drive, AFD or AC Drive. The main purpose of the device is to control of AC induction motors. It controls the speed of motor by generating variable electrical frequency and voltage. Furthermore, it helps in the starting of the motor by taking care of the starting current.

The main working principal of VDF depends of two important steps. Normally the VFDs are AC-AC type. That means, it converts the input AC power of fixed frequency to a AC power to variable AC power. It achieves this by converting the input AC power to DC power. This step is known as Rectification. Then this DC power is converted to AC power again with the help of inverter circuit. The inverter circuit can produce the AC power as per the duty cycle of the SCRs thus can produce any frequency as programmed

In Bangladeshi industrial sector, a lot of suppliers work in the field of VFD. They supply different brands and different rating of inverters. More often small rating inverters are kept in the ready stock by large capacity one may need to import as required.
