    Abstract: A drive circuit is provided for reducing conducted electromagnetic interference provided by a power line to a motor controller. The power line includes a first alternating current (AC) line output and a second AC line output. The drive circuit includes an EMI filter having a first input terminal, a second input terminal, a first output terminal, and a second output terminal. The first input terminal is configured to be coupled to the first AC line output and the second input terminal is configured to be coupled to the second AC line output. The drive circuit further includes at least two series-coupled filter capacitors positioned after the EMI filter and a power factor correction (PFC) choke. The PFC choke is coupled at a first end to the second output terminal and at a second end between the series-coupled filter capacitors.
