Abstract:
A poly-phase motor drive includes an input EMI filter having a poly-phase filter input and a poly-phase filter output and an active rectifier connected to the filter output. The input EMI filter includes notch filters tuned at active rectifier and motor drive inverter switching frequencies and diverts common-mode current into DC bus. The active rectifier has a DC output. A motor drive inverter is connected to the DC output. The motor drive inverter has a poly-phase motor control output.
