    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.

    Abstract: An interleaved bridgeless power factor correction (PFC) converter-based motor drive system is provided. The system includes a first inductor coupled to a second inductor. The coupled first and second inductors are coupled to a first input configured to be coupled to a first line of an alternating current (AC) power supply. The system also includes a third inductor coupled to a fourth inductor. The coupled third and fourth inductors are coupled to a second input configured to be coupled to a second line of the AC power supply. The system further includes a digital active power factor correction (PFC) controller configured to cause current in at least one of the coupled first and second inductors and the coupled third and fourth inductors to be interleaved.

    Abstract: Methods and systems for programming an electric motor are provided. An electric motor controller configured to be coupled to an electric motor is configured to control the electric motor to produce torque when direct current (DC) link voltage has up to 100% voltage ripple. The controller includes a first power input, a second power input, and a third power input, an energized line detection device, and a microprocessor. Each power input is configured to receive power from an alternating current (AC) power source. The energized line detection device is configured to sense which power input has received power from the AC power source and output an isolated signal. The microprocessor is coupled downstream from the energized line detection device and is configured to determine an operating profile for the electric motor based on the isolated signal.

    Abstract: A motor controller having low standby power consumption is provided. The motor controller includes a direct current (DC) bus. The motor controller also includes a low-power supply. The motor controller also includes an inverter configured to control a supply of current to stator windings of a motor. The motor controller also includes a switch circuit coupled between the DC bus and the low-power supply. The motor controller also includes a switch controller coupled to the switch circuit and configured to be coupled to a system controller. The switch controller is configured to control the switch circuit to electrically decouple, in response to detecting an absence of a control signal from the system controller, the DC bus from the low-power supply.
