    • A power converter for effectively reducing switching noise is provided. The power converter comprises a capacitor 111; switching devices Q11a and Q11b connected to the capacitor 111 in parallel; and a controller 105 that controls each switching device individually to perform switching operations. Each of the switching devices Q11a and Q11b forms a closed circuit together with the capacitor 111. The controller 105 controls the switching devices Q11a and Q11b to perform switching operations of switching ON or OFF at different timings such that at least two closed circuits including the switching devices Q11a and Q11b mutually cancel ringing voltages occurring therein, each ringing voltage occurring due to the switching operations performed by a corresponding switching device and having a frequency defined by an inductance of a corresponding closed circuit and an output capacity of a switching device included in the corresponding closed circuit.

    • A method and an apparatus for implementing a semiconductor switch multi-stage drive circuit (103). The disclosed method and an apparatus reduce losses in a semiconductor switch (104) when it is turned from an off state to an on state or from an on state to an off state. The reduction in losses is achieved without influencing the dv/dt across the semiconductor switch (104) during a first time period while the semiconductor switch is switching. This reduction in losses is therefore achieved with very little increase in the noise generated due to rapid dv/dt during the first time period when the semiconductor switch is switching. The configuration of the circuitry to achieve this reduction in switching losses is such that benefits are less sensitive to manufacturing tolerances and temperature effects than alternative semiconductor switch drive schemes to achieve similar results.
