摘要： A dual input power supply is provided, which comprises a dual input, a connector, a power converter circuit and an output. The dual input has a first input and a second input. The connector is an integrated magnetic element used for integrating the input powers having different power signals from the first input and the second input. The power converter circuit comprises an AC-to-DC converter, a DC-to-DC converter, a feedback circuit and a filter circuit. In the present invention, the dual input uses a set of transformer coils or inductive coils, thus the size of the present power supply can be reduced.

摘要： A battery charging device suitable for a portable electronic device includes a rechargeable battery, a controlling chip, an adjusting transistor, a feedback circuit and a charger with adjustable output. The charger has an external alternating-current power source and provides a changeable voltage to the rechargeable battery of the portable electronic device. The feedback circuit captures a signal of electric quantities of the rechargeable battery and feeds back to the charger to adjust its output voltage and then the charger is controlled to charge the rechargeable battery. The adjustable transistor is used to control the charging of the rechargeable battery to reduce the number of parts of the battery charging device and waste of circuit traces.

摘要： The present invention provides a heat sink structure, which includes: a housing located on a material with low thermal conductivity; and a heat conductor placed inside the housing. At least one air gap is formed between the heat conductor and the housing to reduce the conductivity from the heat conductor to the housing, and thus increasing the thermal resistance between the heat conductor and the housing. The surface temperature of the bottom of the housing thus could be reduced and averaged, so as to effectively improve the lifespan, the safety and reliability of a device with the heat sink structure.
摘要翻译：本发明提供一种散热器结构，其包括：位于具有低导热性的材料上的壳体; 和放置在壳体内部的导热体。在导热体和壳体之间形成至少一个气隙，以降低从导热体到壳体的导电性，从而增加导热体与壳体之间的热阻。因此，可以减小和平均壳体底部的表面温度，从而有效地提高具有散热器结构的装置的寿命，安全性和可靠性。
