Abstract: A motor controller executing a current regulator and a modulation routine in separate update intervals provides an improved fundamental voltage waveform for a motor controlled by the motor controller. The current regulator is executed at a first periodic update rate and the modulation routine is executed at a second periodic update rate, where the frequency at which the modulation routine executes is at least twice the frequency at which the current regulator executes. Executing the current regulator and the modulation routines at different frequencies results in the current regulator generating a single voltage reference signal for multiple periods of the modulation routine. To reduce voltage ripple induced by decoupling execution of the current regulator and the modulation routine, the motor controller extrapolates the voltage reference generated by the current regulator into multiple voltage reference signals, where a unique voltage reference signal is provided for each period of the modulation routine.

Abstract: The present techniques include methods and systems for detecting the grounding condition of an electrical system to automatically determine a suitable electrical drive configuration. The drive includes a test resistor which may be connected or disconnected from the drive to measure different drive voltages. The measured drive voltages are analyzed to determine a type of grounding configuration of the electrical system in which the drive is to be installed. Embodiments also include determining ground resistance condition such as a high resistance ground (HRG) fault or a ground resistance fault when the drive is in operation.

Abstract: A system and method for integrating a magnetic component within a power converter includes a coil integrated on a PCB. The PCB includes multiple layers and traces on each layer to form a single coil or to form multiple coils on the magnetic component. The PCB further includes at least one opening in the PCB through which a core component may pass, such that the magnetic component is defined by the coils and the core material. To reduce eddy currents built up within the traces, the dimensions of traces on a layer are varied and the position of traces between layers of the PCB are varied. The widths and locations of individual traces are selected to reduce coupling of the trace to leakage fluxes within the magnetic component. A floating conductive layer may also be provided to still further reduce the magnitude of eddy currents induced within the coil.

Abstract: A motor drive that outputs a sinusoidal waveform utilizes power switching devices operable at high switching frequencies. The switching devices may be operated, for example, between twenty kilohertz and one megahertz. A first filter is included at the output of the motor drive which has a bandwidth selected to attenuate voltage components at the output which are at the switching frequency or multiples thereof such that the output voltage waveform is generally sinusoidal. Additional filtering is included within the motor drive to establish a circulation path for common mode currents within the motor drive. Further, a shield is provided adjacent to those components within the motor drive that may experience voltage or current waveforms at the switching frequency or multiples thereof to cause radiated emissions to establish eddy currents within the EMI shield rather than passing through the shield into the environment.

Abstract: A modulation routine in a motor drive under lightly loaded conditions which prevents DC bus voltage pump-up includes both active states and zero states. In a first zero state, each phase of the motor is connected to a negative rail of the DC bus, and in a second zero state, each phase of the motor is connected to a positive rail of the DC bus. When motor is lightly loaded or unloaded such that DC bus voltage pump-up may occur, the two zero states are utilized in an uneven manner. The specific division of the zero state between the first and second zero states may be selected in a manner that prevents the DC bus voltage pump-up from occurring.

Abstract: A thermal well temperature monitoring assembly with high dielectric strength capability is disclosed consisting of a low relative dielectric constant material in a continuous structure that does not have any air voids or pockets. The low relative dielectric constant structure of the thermal well has at least one internal cavity having an end region. A thermal sensor is at least partially located within the at least one internal cavity. The thermal sensor has one or more wires extending out of the end region of the internal cavity. A first low relative dielectric constant potting material encapsulates at least a portion of the thermal sensor within the internal cavity to remove air voids that decrease dielectric strength. A second low relative dielectric constant potting material fills at least a portion of the end region of the internal cavity to provide mechanical ruggedness and environmental sealing.
