摘要: Gates of a plurality of semiconductor switching elements are electrically connected to a common gate control pattern by gate wires. Sources of the plurality of semiconductor switching elements are electrically connected to a common source control pattern by source wires. The gate control pattern is disposed to interpose the source control pattern between the gate control pattern and each of the plurality of semiconductor switching elements that are connected in parallel and that operate in parallel. Hence, each of the gate wires becomes longer than each of the source wires, and has an inductance larger than the source wire. Accordingly, gate oscillation is reduced or suppressed in the plurality of semiconductor switching elements that are connected in parallel and that operate in parallel.

摘要: A parallel driving device that drives parallel-connected semiconductor elements includes a control unit and a gate driving circuit. The control unit detects a temperature difference between the semiconductor elements on the basis of detected values by temperature sensors that detect temperatures of the individual semiconductor elements. The control unit generates a control signal for changing the timing at which to turn on a first semiconductor element specified from the semiconductor elements on the basis of the temperature difference. The gate driving circuit generates a first driving signal for driving the semiconductor elements, and generates a second driving signal that is the first driving signal delayed on the basis of the control signal, and applies the second driving signal to the first semiconductor element.

摘要: An emitter interconnection connecting the emitter of a semiconductor switching element to a negative electrode is different in one or both of length and width from an emitter interconnection connecting the emitter of a semiconductor switching element to the negative electrode. At the time of switching, an induced electromotive force is generated at a gate control wire, or at a gate pattern, or at an emitter wire, by at least one of a current flowing through a positive electrode and a current flowing through the negative electrode, so as to reduce the difference between the emitter potential of the semiconductor switching element and the emitter potential of the semiconductor switching element caused by the difference.

摘要: A classification circuit generates first information for classifying an operating state of a power semiconductor element into one of a plurality of predetermined operating regions. A selector circuit generates second information for selecting a plurality of modes with different switching speeds, based on a user input. A characteristic control circuit stores a drive adjustment signal in advance for each of combinations of the operating regions and the modes and outputs the drive adjustment signal in a combination of one operating region and one mode that is selected in accordance with the first information and the second information. A gate drive circuit charges/discharges a gate at a charge rate and a discharge rate variably set in accordance with the drive adjustment signal from the characteristic control circuit, at the time of on/off of the power semiconductor element.

摘要: A power semiconductor module includes a base plate as a metallic heat dissipating body, a first insulating layer on the base plate, and a first wiring pattern on the first insulating layer. On a predetermined region that is a part of the first wiring pattern, a second wiring pattern for a second layer is laminated via only a second insulating layer made of resin, thereby forming a pattern laminated region. A power semiconductor element is mounted in a region other than the pattern laminated region on the first wiring pattern. The base plate, the first insulating layer, the first wiring pattern, the second insulating layer, the second wiring pattern, and the power semiconductor element are integrally sealed with a transfer mold resin, thus obtaining the power semiconductor module.
