摘要： An oil-cooled inverter for an electric traction motor that uses six IGBT switches to generate 3-phase AC electrical current as its output. The switches are mounted on heat sinks that use hot motor oil (hydraulic fluid) as the heat transfer fluid. An interior of each of the heat sinks contains a heat transfer medium. The heat sink housing is made of molybdenum, which has a thermal expansion rate equal to that of silicon. This allows the circuitry of the inverter to be mounted directly on the top surface of the heat sinks, as the expansion and contraction of the heat sink housing will match that of the silicon substrate of the chips. Since both elements, the heat sink housing and the chip substrate, expand and contract at an equal rate during heating and cooling, the problem of the chip substrate cracking and breaking due to thermal flexing is eliminated. The inverter is in most ways electrically equivalent to prior art inverters, but the upper surface formed by the bank of heat sinks is electrically hot, and is used as part of the inverter circuitry. This allows the elimination of the insulating plate on which the inverter circuitry is normally mounted, as the chips of the inverter circuitry are mounted directly on the upper surface of the heat sinks of the inverter.

摘要翻译： 用于电动牵引电动机的油冷逆变器，其使用六个IGBT开关来产生三相交流电流作为其输出。 开关安装在使用热机油（液压油）作为传热流体的散热器上。 每个散热器的内部包含传热介质。 散热器壳由钼制成，其热膨胀率等于硅的热膨胀率。 这样就可以将逆变器的电路直接安装在散热器的顶面上，因为散热器壳体的膨胀和收缩将与芯片的硅衬底的膨胀和收缩相匹配。 由于两个元件，散热器壳体和芯片基板在加热和冷却期间以相同的速率膨胀和收缩，所以消除了由于热弯曲引起的芯片基板的破裂和断裂的问题。 逆变器在大多数方面与现有技术的逆变器电气相当，但是由散热器组形成的上表面是电热的，并且被用作逆变器电路的一部分。 由于逆变器电路的芯片直接安装在逆变器的散热片的上表面上，所以能够消除正反面安装有逆变器电路的绝缘板。

摘要： A module is formed in which semiconductor components are soldered to an electrically conductive heat sink. The electrically conductive heat sink is formed so that it will serve as an electrical bus in an electronic device. The chips of the semiconductor component are metallurgically bonded to the surface of the heat sink. The heat sink uses a heat transfer fluid that flows through an interior of the heat sink, the interior containing an internal element. In the preferred embodiment, the internal element is a plurality of silver plated copper balls. The copper balls are brazed to each other and to the walls of the heat sinks in an assembly process. The heat sink housing will typically be made from copper, with one surface made from molybdenum so that the expansion and contraction of the heat sink housing molybdenum surface will be similar to that of the silicon substrate of the chips, thereby avoiding the problem of the chip substrate cracking and breaking due to thermal flexing.

摘要： An adapter circuit in power supplies utilizes a selective voltage doubler which approximately doubles an input voltage with a low line connector and does not with a high line connector. The selective voltage doubler is coupled to a switcher, which in turn is coupled to a resonant circuit. The resonant circuit is coupled to a first diode and a second diode and a filter. When a low line connector is used, the input voltage is doubled and a one diode drop is used. When a high line connector is used, the input voltage is not doubled and a two diode drop is used.
