Abstract: A pressure sensor includes a diaphragm, a coupling portion coupled to the diaphragm, and two pressure receiving elements. Each pressure receiving element outputs an output signal that changes according to the temperature and the pressure applied to a pressure receiving surface and has an output characteristic that represents the relationship of the output signal to the pressure and the temperature. The two pressure receiving elements have the same output characteristics. The pressure receiving surface of one of the two pressure receiving elements is connected to the diaphragm through the coupling portion, and the pressure receiving surface of the other pressure receiving element is disconnected from the diaphragm. The pressure sensor outputs a signal that is in accordance with the difference between voltages of the two pressure receiving elements.

Abstract: A semiconductor device includes: at least one power semiconductor element; a sealing resin disposed so as to seal the power semiconductor element; and a plurality of electrical terminals each electrically connected to the power semiconductor element and each including a protrusion protruding from a surface of the sealing resin. The protrusion includes a first part that is provided on a side of the sealing resin in a protrusion direction of the protrusion and of which a cross-section intersecting the protrusion direction has one of a circular shape and an oval shape.

Abstract: In a converter circuit of an electric power conversion device, an adjustment portion divides a voltage of a battery input to a semiconductor module, by a first capacity element and a second capacity element that are connected in series to each other. Then, a middle point between the first capacity element and the second capacity element is connected to a cooler to fix a potential thereof. The electric power conversion device can ensure that a waveform of a surge voltage that is generated on a creepage surface between a lead frame terminal and the cooler has a negative voltage range (a range where an offset voltage is applied).
