Abstract: A method of operating an electric motor is disclosed. The method includes: determining a d-axis resistance of an electric motor and a Q-axis resistance of the electric motor as a function of a bulk current; determining a d-axis inductance of the electric motor and a Q-axis inductance of the electric motor as a function of the bulk current; generating an estimated flux of the electric motor based on the d-axis resistance of the electric motor, the Q-axis resistance of the electric motor, the d-axis inductance of the electric motor, and the Q-axis inductance of the electric motor; generating an estimated angle of the electric motor based on the estimated flux of the electric motor; and, based on the estimated angle of the electric motor, controlling switching of an inverter that powers the electric motor.

Abstract: A drive circuit is provided and includes a rectification circuit, a buck converter, a first inverter, and a second inverter. The rectification circuit is configured to rectify a first AC voltage signal to generate a rectified voltage signal. The buck converter is configured to downconvert the rectified voltage signal to a DC voltage signal, wherein the DC voltage signal is supplied to a DC bus. The first inverter is configured to convert the DC voltage signal to a second AC voltage signal and supply the second AC voltage signal to a compressor motor. The second inverter is configured to convert the DC voltage signal to a third AC voltage signal and supply the third AC voltage signal to a condenser fan motor. Peak voltages of the second AC voltage signal and the third AC voltage signal are less than peak voltages of the first AC voltage signal.

Abstract: A controller includes a voltage determination module, a bus voltage command module, and a power factor correction (PFC) control module. The voltage determination module determines a desired direct current (DC) bus voltage for a DC bus electrically connected between a PFC module and an inverter power module that drives a motor. The voltage determination module determines the desired DC bus voltage based on at least one of torque of the motor and speed of the motor. The bus voltage command module determines a commanded bus voltage based on the desired DC bus voltage. The PFC control module controls the PFC module to create a voltage on the DC bus that is based on the commanded bus voltage.

Abstract: A control system for a motor includes a pulse-width modulation module, a pulse skip determination module, and a duty cycle adjustment module. The pulse-width modulation module generates three duty cycle values based on three voltage requests, respectively. A plurality of solid-state switches control three phases of the motor in response to the three duty cycle values, respectively. The pulse skip determination module generates a pulse skip signal. The duty cycle adjustment module selectively prevents the plurality of solid-state switches from switching during intervals specified by the pulse skip signal.

Abstract: A control system for driving a motor of a compressor includes a microcontroller and a programmable logic device. The microcontroller is configured to generate a reference current value for a power factor correction (PFC) converter. The programmable logic device is configured to receive control messages from the microcontroller and, in response to data in a first control message, set a value into a timing register. The programmable logic device is configured to reverse a state of a power switch of the PFC converter between an on state and an off state in response to receiving a comparison signal indicating that a measured current in the PFC converter crossed the reference current value. The programmable logic device is configured to, subsequent to reversing the state of the power switch, wait for a period of time determined by the timing register and reverse the state of the power switch.

Abstract: A refrigeration system includes a startup mode control module that receives at least one parameter associated with operation of a compressor of the refrigeration system, determines whether the at least one parameter indicates that the compressor is in a high ambient temperature startup condition, and selects, based on the determination, between a normal startup mode and a high ambient temperature startup mode. A compressor control module operates the compressor in the normal startup mode in response to the startup mode control module selecting the normal startup mode, operates the compressor in the high ambient temperature startup mode in response to the startup mode control module selecting the high ambient temperature startup mode, and transitions from the high ambient temperature startup mode to the normal startup mode after a predetermined period associated with operating in the high ambient temperature startup mode.
