Abstract: An integrated drive motor (IDM) power distribution architecture utilizes an IDM power interface module (IPIM) to create a control voltage that is distributed to all the IDMs in a network. This power distribution may be accomplished along a hybrid cable, for example, that includes both signal conductors and power conductors. The IPIM is capable of detecting short circuits and/or overload conditions and disabling the power supply to the IDMs. Additionally, a second power supply may be utilized in the IPIM such that when the power supply to the IDMs is deactivated, the IPIM may remain functional, for example, to report one or more fault conditions to the user. Additionally, this reporting of fault status may be accomplished via a user display integrated with or coupled to the IPIM.

Abstract: Power semiconductor switching devices in an integrated motor drive are mounted directly to a circuit board substrate via a “pick and place” assembly process. The circuit board substrate is then mounted within the housing for the integrated motor drive and, preferably, in a generally central orientation within the housing. A potting material is provided within the housing of the integrated motor drive and around the circuit board. The potting material substantially encloses the circuit board and fills the volume within the integrated motor drive. The potting material is selected to provide good thermal conductivity between the circuit board and the housing of the integrated motor drive. The potting material is also selected to provide flexibility such that expansion and contraction of the potting material due to heating and cooling of the material does not damage the circuit board or the electronic components mounted to the circuit board.

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: 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.
