Abstract
An EMI filter is described that includes an input having first and second input terminals, and an output having first and second output terminals. A first conductive path is defined between the first input and output terminals, and a second conductive path is defined between the second input and output terminals. The EMI filter also includes a first choke device coupled across the first and second conductive paths, and a first Y capacitor including a first end and a second end opposite the first end, the first end coupled to the first conductive path downstream from the first choke device. The EMI filter further includes a second Y capacitor including a first end and a second end opposite the first end, the first end coupled to the second conductive path downstream from the first choke device, and a second choke device coupled to an inverter output.
