    Abstract: A power module includes a insulation substrate, a first and a second input terminal supported by the insulation substrate, a plurality of arm circuits provided on the insulation substrate, and a plurality of output terminals corresponding to the plurality of arm circuits. The arm circuits each include a part of a wiring pattern formed on the insulation substrate, and a first switching element and a second switching element mutually connected in series via the part of the wiring pattern. The output terminals are each connected to a connection point between the first switching element and the second switching element in a corresponding one of the plurality of arm circuits. The plurality of arm circuits are located so as to overlap with a circle surrounding the first input terminal, as viewed in a thickness direction the insulation substrate.

    Abstract: The disclosure relates to printed circuit board motors and specifically to printed circuit boards used in motors and generators. Windings formed from copper on printed circuit boards have been used for purposes of forming antennas, inductors, transformers, and stators that can be incorporated in permanent magnet brushless DC (permanent magnet synchronous) machines. For energy conversion devices using modern permanent magnet materials and PCB stators, the magnetic field is not strongly confined by magnetically susceptible materials. Thus, the interaction between fields from adjacent turns in a winding, and/or windings on adjacent layers (for a multilayer configuration) may be significant. The structures disclosed hereinafter reduce the effective resistance in the windings, and therefore reduce the associated losses to achieve a reduced current density in portions of the rotating energy conversion devices. The effect of the disclosed structures is a measurable reduction in loss mechanisms as a function increasing frequency, compared to the currently available devices. These effects are significant in frequency ranges important to energy conversion processes as well as typical control strategies, for example, pulse-width modulation.

    Abstract: The invention relates to a conductor track unit, in particular for a motor vehicle. The conductor track unit is provided with conductor tracks which are embedded in an electrically insulating material. The conductor tracks are, in particular completely, surrounded by the electrically insulating material and are therefore not accessible from the outside. Electrical connections are electrically connected to the conductor tracks. The electrical connections are accessible from the outside, and therefore can be electrically connected to electrical contacts of electrical or electronic components such as a switch, detector, electronic radio component, integrated circuit, electronic chip, electronic control device or motor, for example by soldering. The conductor tracks and electrical connections are different components which are therefore initially independent of one another and can be produced independently dependently of one another. A particularly robust yet delicate conductor track unit can be provided in this way.

    Abstract translation: 本发明涉及导体轨道单元，特别是用于机动车辆。 导体轨道单元设置有嵌入电绝缘材料的导体轨迹。 导体轨道特别完全被电绝缘材料包围，因此不能从外部接近。 电连接电连接到导体轨道。 电连接可以从外部访问，因此可以电连接到诸如开关，检测器，电子无线电部件，集成电路，电子芯片，电子控制装置或电机之类的电气或电子部件的电触点，例如通过焊接 。 导体轨道和电连接是不同的部件，因此它们最初彼此独立并且可以彼此独立地相互制造。 这样可以提供一个特别坚固而精细的导轨跟踪单元。
