FUJI IGBT Module 7MBR25SA120-60 1200V/25A Inverter-VFD-Ac Servo Drive in Dhaka-BD. It is most of important parts for repair Inverter-VFD, How to find out IGBT Faults in the VFD Control circuit? Why we can use IGBT in inverter-VFD?
IGBT Means Insulated Gate Bipolar Transistor. The IGBT combines an remoted-gate FET for the manage enter and a bipolar power transistor as a switch in a single tool. The IGBT is used in medium to high–strength packages like switched-mode power materials, traction motor control and induction heating. it makes DC to AC in the Inverting circuit
The Insulated Gate Bipolar Transistor Produce high voltage by the gate switching, Transistor makes low voltage power in the inverter control.
