Abstract: A circuit for driving a motor of a compressor includes a microcontroller, which includes an op-amp, a comparator, a first serial interface, and a first dedicated pin. The op-amp amplifies a value indicating current in a power factor correction converter, which includes a power switch. The comparator asserts a comparison signal in response to the amplified value exceeding a reference value. The comparison signal is output on the first dedicated pin. A programmable logic device (PLD) includes a second serial interface in communication with the first serial interface and a second dedicated pin. The comparison signal is received on the second dedicated pin and the PLD receives control messages from the microcontroller via the second serial interface. The PLD sets a value in an off-time register based on a control message from the microcontroller. The PLD controls the power switch according to the comparison signal and the off-time register.

Abstract: A control system for a refrigeration system motor includes an angle determination module that generates an output rotor angle indicating a desired angle of a rotor of the motor. A control module controls the motor based on the output rotor angle. An estimator module determines an estimated rotor angle. A transition module generates a transition signal in response to convergence of the estimator module. Upon startup, the angle determination module generates the output rotor angle based on a first rotor angle. Upon generation of the transition signal, the angle determination module generates the output rotor angle based on the first rotor angle and the estimated rotor angle. After generation of the transition signal, the angle determination module reduces a contribution of the first rotor angle to the output rotor angle over time until the output rotor angle is based on the estimated rotor angle independent of the first rotor angle.

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.

Abstract: A control system for a motor in a refrigeration system includes an angle determination module configured to generate an output rotor angle indicative of a desired angle of a rotor of the motor. The control system controls current supplied to the motor based on the output rotor angle. The control system determines an estimated rotor angle of the motor. The angle determination module, upon startup of the motor, generates the output rotor angle based on a first rotor angle. Upon generation of a transition signal, the angle determination module generates the output rotor angle based on both the first rotor angle and the estimated rotor angle. Subsequent to generation of the transition signal, the angle determination module reduces a contribution of the first rotor angle to the output rotor angle over time until the output rotor angle is based on the estimated rotor angle independent of the first rotor angle.

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 drive for a mobile compressor includes EMI and transient protection circuits, second chokes, converters and an inverter. The EMI and transient protection circuits include respectively common mode chokes and at least one component. Each of the common mode chokes is configured to receive a first direct current voltage and is connected to first and second grounds. The at least one component is connected to a third ground. The first, second and third grounds are at different voltage potentials. The second chokes are connected downstream from the common mode chokes. The converters are connected to outputs of the second chokes and are configured to collectively provide a second direct current voltage to a direct current bus. The inverter is connected to the direct current bus and configured to convert the second direct current voltage to an alternating current voltage to power the mobile compressor downstream from the inverter.

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.
