Abstract: A thermoelectric power generation device includes a plurality of units that are stacked, each unit including a thermoelectric module containing at least one thermoelectric element, and a first plate and a second plate interposing the thermoelectric module therebetween, wherein a spacer is interposed between a surface of one of the first plates facing away from the corresponding thermoelectric module and a surface of the opposing second plate facing away from the corresponding thermoelectric module, the spacer contacting the first plate and the second plate and defining a fluid passage jointly with the first plate and the second plate, and wherein the fluid passages defined between the adjacent units are configured to receive supply of high temperature fluid and low temperature fluid in an alternating manner in a stacking direction of the units. The plates can be conformed to the thermoelectric module, and the stiffness of the plate can be increased.

Abstract: A transformer includes a primary winding, a secondary winding, a first core, and a second core. The primary winding and the secondary winding are inserted into the first core and the second core, and the first core and the second core are disposed to face each other. The first core includes one first core portion, and the second core includes a plurality of second core portions. The first core is a lower core, and the second core is an upper core. The first core and the second core are disposed to face each other with a gap interposed between the first core and the second core. The first core and the second core include a heat-resistant elastic body in the gap, and are disposed to face each other. Each of the second core portions is disposed with a heat-resistant elastic body interposed between the second core portions.

Abstract: A power conversion apparatus is provided with: a plurality of power conversion circuits each provided with a transformer and supplying DC power to a common rechargeable battery; a control circuit configured to control the power conversion circuits; and a cooling device configured to cool the power conversion circuits. The cooling device is provided with at least one flow path for a coolant, the flow path being in thermal contact with the transformers of the power conversion circuits. When a load voltage of the rechargeable battery is equal to or higher than a predetermined threshold, the control circuit operates one power conversion circuit of the plurality of power conversion circuits, the one power conversion circuit provided with the transformer having a largest thermal contact area with the flow path, and stops operations of other power conversion circuits of the plurality of power conversion circuits.

Abstract: A power conversion apparatus is provided with: a plurality of power conversion circuits each provided with a transformer and supplying DC power to a common rechargeable battery; and a control circuit configured to control the plurality of power conversion circuits. When a load voltage of the rechargeable battery is equal to or higher than a first threshold, the control circuit selectively and sequentially operates the plurality of power conversion circuits such that one of the plurality of power conversion circuits is operated, and others of the plurality of power conversion circuits are stopped.
