THE 5-SECOND TRICK FOR VFD

Let's assume the travel is running over a 480V energy method. The 480V rating is “rms” or root-indicate-squared. The peaks on a 480V method are 679V. As you could see, the VFD dc bus provides a dc voltage having an AC ripple. The voltage operates among around 580V and 680V.The IGBTs here act like switches that when promptly switched on and off,
