    Abstract: A system to monitor the temperature of power electronic devices in a motor drive includes a base plate defining a planar surface on which the electronic devices and/or circuit boards within the motor drive may be mounted. The power electronic devices are mounted to the base plate through the direct bond copper (DBC). A circuit board is mounted to the base plate which includes a temperature sensor mounted on the circuit board proximate to the power electronic devices. The temperature sensor generates a digital signal corresponding to the temperature measured by the sensor. A copper pad is included between each layer of the circuit board and between the first layer of the circuit board and the sensor. The circuit board also includes vias extending through each layer of the board. The copper pads and vias establish a thermally conductive path between the temperature sensor and the base plate.

    Abstract: A system for distributing DC bus voltage and control power to multiple motors includes a rectifier front end supplying a DC bus voltage and a DC control voltage. Both the DC bus voltage and the DC control voltage are distributed via a common set of conductors. Diodes are operatively connected between the DC control voltage and the common set of conductors. The diodes allow forward conduction of the DC control voltage and distribution of control power to distributed devices when the DC bus voltage is not present. Once the DC bus voltage is present, the diodes block conduction of the DC control voltage. Each of the distributed devices are configured with an internal power supply that is operative to generate an internal control voltage from either the DC control voltage or the DC bus voltage.

    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 cable for reducing electrical noise within a distributed motor drive system includes an insulating jacket defining an outer periphery of the cable. The insulating jacket extends between a first end and a second end of the cable. At least one power conductor and a ground conductor extend between the first and second ends of the cable. A communication cable also extends between the first and second ends of the cable. The communication cable includes a second jacket having an outer surface and an inner surface, where the outer surface of the second jacket defines an outer periphery of the communication cable. At least one pair of communication conductors and a braided shield extend within the communication cable. The braided shield is positioned around the communication conductors and is electrically connected to the ground conductor at the first and second ends of the cable.

    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 translation: 集成驱动电机(IDM)配电架构使用IDM电源接口模块(IPIM)来创建分配给网络中所有IDM的控制电压。 该功率分布可以沿着例如包括信号导体和电力导体的混合电缆来实现。 IPIM能够检测短路和/或过载条件,并禁用对IDM的供电。 此外,IPIM中可以使用第二电源,使得当对IDM的电源被去激活时,IPIM可以保持功能,例如向用户报告一个或多个故障状况。 此外,故障状态的报告可以通过与IPIM集成或耦合到IPIM的用户显示来实现。
