    • The invention discloses a manufacture method and structure of a power transistor, comprising a lower electrode, a substrate, a drift region, two first conductive regions, two second conductive regions, two gate units, an isolation structure and an upper electrode. The two second conductive region are between the two first conductive regions and the drift region; the two gate units are on the two second conductive regions; the isolation structure covers the two gate units; the upper electrode covers the isolation structure and connects to the two first conductive regions and the two second conductive regions electrically. When the substrate is of the first conductive type, the structure can be used as MOSFET. When the substrate is of the second conductive type, the structure can be used as IGBT. This structure has a small gate electrode area, which leads to less Qg, Qgd and Rdson and improves device performance.

    • The continuous conduction mode (CCM) boost voltage power factor correction apparatus with an average-current control mode of the present invention uses resettable integrators to integrate the difference voltage signal outputted from the voltage error amplifier and the input current signal obtained from detection. The integration results are then compared to control the duty cycle of the switch. Thereby, the input current and the input voltage in the AC/DC electrical power converter have a proportion relation and their phases are the same as each other. The components used in this control method are simpler than the PFC circuit of the prior art. It is easy to integrate in one chip with fewer pins. The apparatus of the present invention has a high power factor and a low total harmonic distortion (THD).
    • 具有本发明的平均电流控制模式的连续导通模式(CCM)升压电压功率因数校正装置使用可复位积分器来积分从电压误差放大器输出的差分电压信号和从检测获得的输入电流信号。 然后将积分结果进行比较,以控制开关的占空比。 因此,AC / DC电力转换器的输入电流和输入电压具有比例关系,它们的相位彼此相同。 在该控制方法中使用的部件比现有技术的PFC电路简单。 在一个芯片中集成更少的引脚很容易。 本发明的装置具有高功率因数和低总谐波失真(THD)。

    • A high-speed, solid-state circuit breaker is capable of interrupting high DC currents without generating an arc, and it is maintenance-free. Both the switch and the tripping unit are solid-state, which meet precise protection requirements. The high-speed, solid-state DC circuit breaker uses an emitter turn-off (ETO) thyristor as the switch. The ETO thyristor has an anode, a cathode and first, second and third gate electrodes. The anode is connectable to a source of DC current, and the cathode is connectable to a load. A solid-state trip circuit is connected to the first, second and third gate electrodes for controlling interrpution of DC current to the load by turning off said ETO thyristor.
