    • A gate driving circuit and method can improve the tradeoff relation between the noise and the loss caused in the turn-OFF switching of semiconductor device. The gate driving circuit includes first and second series circuits. The first series circuit includes first and second MOSFETs connected in series. The gate terminal of the semiconductor device is connected to a negative potential side of the first MOSFET and a positive potential side of the second MOSFET. The emitter of the semiconductor device is connected to the negative potential side of the second MOSFET or a DC power source. The second series circuit includes a capacitor and a third MOSFET connected in series. The second series circuit is connected in parallel with the second MOSFET. The semiconductor device is turned OFF by turning ON the second and third MOSFETs and turning OFF the first MOSFET.

    • A semiconductor power module includes a filter element made of a magnetic material that can be exchanged as required, while providing a package having a compact size. The power module can be used for a power conversion device for providing power conversion of DC power or AC power by switching a power semiconductor element, such as an IGBT. The filter element can be an annular magnetic member that rests around one or more terminals connected to the power semiconductor element. Noise current flowing through the terminals, when the power semiconductor element is switched, can be suppressed effectively with the annular magnetic member.
    • 半导体功率模块包括由可以根据需要更换的磁性材料制成的过滤元件,同时提供具有紧凑尺寸的封装。 功率模块可以用于通过切换诸如IGBT的功率半导体元件来提供直流电力或交流电力的电力转换的电力转换装置。 过滤元件可以是围绕连接到功率半导体元件的一个或多个端子的环形磁性构件。 当功率半导体元件被切换时,流过端子的噪声电流可以通过环形磁性元件被有效地抑制。
