Mitsubishi inverter works
Mitsubishi inverter is the use of power semiconductor devices on and off the power frequency power supply into another frequency of the power control device. We are now using the inverter is mainly used to pay – straight – cross mode (VVVF frequency or vector control frequency), the first frequency AC power through the rectifier into a DC power supply, and then convert the DC power supply frequency, voltage can be controlled AC power supply to the motor. The inverter circuit is usually composed of rectifier, intermediate DC link, inverter and control four parts. Rectifier part of the three-phase bridge uncontrollable rectifier, inverter part of the IGBT three-phase bridge inverter, and the output for the PWM waveform, the middle of the DC link for the filter, DC energy storage and buffer reactive power.
