発明の名称 (英語) IMPEDANCE ADJUSTMENT CIRCUIT, POWER CONVERSION ELEMENT, AND POWER SUPPLY ELEMENT NEW
発明の概要(英語) An adjustment circuit 9 is connected between a power generation circuit 8 that converts environmental energy into electrical power and a power conversion circuit 11 that converts the power generation circuit 8 electrical power into a desired form. The adjustment circuit 9 is provided with a first circuit part 13 and a second circuit part 14. The first circuit part 13 has an input 9a connected to the power generation circuit 8 and an output 9c connected to the power conversion circuit 11. The second circuit unit 14 has a connection point P1 connected to the first circuit part 13, a grounding point P2 connected to a ground potential (GND), and a capacitor C connected between the connection point P1 and the grounding point P2. The size of an output resistance 14R included in the second circuit part 14 is smaller than the size of an output resistance 8R included in the power generation circuit 8. The capacitor C is charged with the electrical power outputted from the power generation circuit 8, and outputs the charged electrical power to the power conversion circuit 11.
