Harmonic effect between VSI and CSI using PWM control scheme

The voltage source inverter (VSI) and current source inverter (CSI) are the type of inverters that commonly used today and mostly PWM (pulse width-modulation) drives. The functions of the inverters are for conversion from ac to dc source. These simulations are implemented in the PSIM program in orde...
