Abstract: Controllers for controlling hybrid motor drive circuits configured to drive a motor are provided herein. A controller is configured to drive the motor using an inverter when a motor commanded frequency is not within a predetermined range of line input power frequencies, and couple line input power to an output of the inverter using a first switch device when the motor commanded frequency is within the predetermined range of line input power frequencies.

Abstract: A motor controller for an electric motor for driving a blower to generate an airflow. The motor controller includes a processor and a drive circuit configured to regulate power supplied to the motor to turn the blower. The processor computes a system resistance for the blower based on a fixed set point for a first control parameter and a feedback parameter. The processor receives an airflow rate demand value and computes an operating set point for a second control parameter based on the system resistance and the airflow rate demand value. The processor controls the drive circuit based on the operating set point to supply electrical power to the electric motor and to operate the blower to generate the airflow.

Abstract: A motor controller and methods for operating a motor are described herein. The motor controller includes a high-frequency (HF) inverter having a direct current (DC) input stage and an alternating current (AC) output stage, the HF inverter operable at a switching frequency to generate a three-phase output having a fundamental frequency. The motor controller also includes a differential mode (DM) filter coupled in series with the output stage of the HF inverter and having a resonant frequency less than 10% of the switching frequency, the DM filter configured to reduce harmonic components of the three-phase output and generate a first filtered output. The motor controller further includes a common mode (CM) filter coupled in series with the DM filter, the CM filter configured to filter the first filtered output to generate a second filtered output having a reduced CM voltage to operate the electric motor with a reduced bearing current.

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: A motor control system for heating, ventilation, and air conditioning (HVAC) applications is described. The motor control system includes a thermostat and an electronically commutated motor (ECM) coupled to the thermostat. The ECM is configured to retrofit an existing non-ECM electric motor included in an HVAC application and to operate in one of a plurality of HVAC modes. The HVAC modes include at least one of a heating mode, a cooling mode, and a continuous fan mode. The HVAC mode is determined based at least partially on outputs provided by the thermostat.

Abstract: A controller and methods for hybrid operation control of an electric motor in an electric motor system are provided. The controller is configured to receive a speed command for operating the electric motor, measure available voltage on an inverter configured to provide conditioned AC voltage to the electric motor, and determine a winding phase angle difference based on the received speed command and the measured available inverter voltage. The controller is also configured to adjust a phase angle difference between winding voltage commands for the switches of the inverter using the determined winding phase angle difference, and apply the winding voltage commands including the adjusted phase angle difference to the inverter switches to control the electric motor.
