How PWM works in IGBT Rectifier VFD, PWM, STATCOM

How pulse width modulation PWM in IGBT based rectifier for VFD / VVVF, STATCOM works, is explained in the video tutorial. PWM (pulse width modulation) technology is used for IGBT based rectifier in VFD/VVVF for train engine, an electric locomotive and also in STATCOM for reactive power control. The Full form of VFD is the variable frequency drive. The full form of VVVF is the variable voltage variable frequency drive. IGBT and pulse with modulation (PWM) based rectifier for variable frequency drive is designed using IGBT and diode both in the rectifier along with one inductor at the input supply. IGBT is switched ON and OFF at high frequency using the PWM concept to control the input current, voltage across inductor and output DC voltage. It provides many advantages like unity power factor, very low harmonics, variable and controlled DC voltage, suitable for large voltage variation and frequency at the input, and power regeneration during application of the brake. Use of IGBT in the rectifier bridge, Operation of IGB and diode to control input current and charging of the capacitor is explained. Educational video tutorial on electricity, power electronics and electrical engineering 292 by G K Agrawal (Gopal Krishna Agrawal). Further, the concept and working principle of the pulse width modulator PWM to control current explained in this video is also useful for STATCOM, reactive power control, SVC for load balancing and power factor control also.
