Abstract: A circuit for driving a motor of a compressor includes a microcontroller that generates a reference current value for a power factor correction (PFC) converter. A programmable logic device (PLD) receives control messages from the microcontroller. The PLD sets a value in an off-time register based on a control message from the microcontroller. The PLD controls a power switch of the PFC converter to turn off in response to receiving a comparison signal indicating that a measured current in the PFC converter exceeds the reference current value. Subsequent to controlling the power switch to turn off, the PLD waits for a period of time determined by the off-time register before controlling the power switch to turn on.

Abstract: A PFC circuit is provided. A bridge rectification circuit receives an AC voltage and generates a rectified AC voltage. A power converter converts the rectified AC voltage to a first DC voltage, where the power converter includes a switch and supplies the first DC voltage to a DC bus to power a compressor. A current sensor detects an amount of current. A control module, while operating in a correction mode: based on the rectified AC voltage, a phase angle of the rectified AC voltage, a second DC voltage of the DC bus, or the detected amount of current, control operation of the switch to transition between operating in a high activity mode and an inactive or low activity mode; transition the switch between open and closed states while in the high and low activity modes; and maintain the power converter in an OFF state while in the inactive mode.

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 a motor includes an angle determination module, a control module, an angle generation module, and an estimator module. The angle determination module generates an output rotor angle indicative of a desired angle of a rotor of the motor. The control module controls current supplied to the motor based on the output rotor angle. The angle generation module generates a commanded rotor angle in response to a commanded speed. The estimator module determines an estimated rotor angle of the motor. Upon startup of the motor, the angle determination module generates the output rotor angle based on the commanded rotor angle. Upon beginning of a transition period, the angle determination module generates the output rotor angle based on the commanded rotor angle and the estimated rotor angle. Upon ending of the transition period, the angle determination module generates the output rotor angle based on the estimated rotor angle.

Abstract: A PFC circuit is provided. A first bridge rectifier receives an AC voltage. A power converter includes a switch and receives an output of the first bridge rectifier, converts the output to a first DC voltage, and supplies the first DC voltage to a DC bus to power a compressor. A second bridge rectifier receives the AC voltage and bypasses at least one of the first bridge rectifier, a choke and a diode of the PFC circuit to provide a rectified AC voltage out of the second bridge rectifier to the DC bus to power the compressor. A control module controls operation of a driver to transition the switch between open and closed states to adjust a second DC voltage on the DC bus, where the second DC voltage, depending on the AC and second DC voltages, is based on the first DC voltage or the rectified AC voltage.

Abstract: A converter circuit is provided and includes: a first EMI filter connected to AC lines and includes one or more across-the-line capacitors; a charging circuit that receives power from the first EMI filter and limits an amount of current passing from the first EMI filter to a DC bus; and a PFC circuit of a compressor drive that provides PFC between an output of the charging circuit and a generated first DC voltage. The PFC circuit includes: a rectification circuit that rectifies the power from the AC lines or a charging circuit output; and a second EMI filter connected downstream from the rectification circuit and including a DC bus rated capacitor. The second EMI filter outputs a filtered DC signal based on a rectification circuit output. The PFC circuit, based on the second EMI filter output, outputs the first DC voltage to the DC bus to power the compressor drive.
