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 system includes a compressor having a shell housing a compression mechanism driven by an electric motor in an on state and not driven by the electric motor in an off state. The system also includes a variable frequency drive that drives the electric motor in the on state by varying a frequency of a voltage delivered to the electric motor and that supplies electric current to a stator of the electric motor in the off state to heat the compressor.

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 desired OFF period module is configured to determine a desired OFF period for a plurality of switches of a PFC circuit based on an input voltage and an output voltage. A blanking timer module is configured to output a blanking signal, set the blanking signal to a first state when a countdown timer is greater than zero, and set the blanking signal to a second state when the countdown timer reaches zero. A switching control module is configured to: transition a first switch of the plurality of switches from an ON state to an OFF state in response to (i) a measured current through an inductor of the PFC circuit being greater than a demanded current through the inductor and (ii) the blanking signal being in the second state; and maintain the first switch in the OFF state for the desired OFF period after the transition.

Abstract: A drive includes an inverter power circuit that applies power to an electric motor of a compressor from a direct current (DC) voltage bus. A power factor correction (PFC) circuit outputs power to the DC voltage bus based on input alternating current (AC) power. The PFC circuit includes: (i) a switch having a first terminal, a second terminal, and a control terminal; (ii) a driver that switches the switch between open and closed states based on a control signal; (iii) an inductor that charges and discharges based on switching of the switch; and (iv) a circuit that outputs a signal indicating whether the switch is in the open state or the closed state based on a voltage across the first and second terminals of the switch.

Abstract: A power factor correction (PFC) system includes a PFC circuit that receives an alternating current (AC) voltage and that, using a switch, generates a direct current (DC) voltage from the AC voltage. A zero crossing module determines a zero crossing of the AC voltage based on: a first voltage and a first time when the AC voltage transitioned from less than a first predetermined voltage to greater than the first predetermined voltage; and a second voltage and a second time when the AC voltage transitioned from less than a second predetermined voltage to greater than the second predetermined voltage. The first predetermined voltage is negative, and the second predetermined voltage is positive. A reference module, based on the zero crossing, generates a sinusoidal reference signal corresponding to the AC voltage in phase and frequency. A switching control module controls switching of the switch based on the sinusoidal reference signal.
