Electrical machine drives used for induction motors are driven by the utility su

Electrical machine drives used for induction motors are driven by the utility supply. It is required to provide a dc voltage for the inverter of the electric machine drives. This is achieved by rectifying the utility supply voltage. Discuss possible rectifier circuits for this function. Assume that utility supply is rated at 400 V, 50 Hz.
