Abstract: An electrochemical device disclosed includes a positive electrode, a negative electrode, and a lithium ion conductive electrolyte. The positive electrode includes a positive electrode mixture layer containing a positive electrode active material. The positive electrode active material contains particles of a conductive polymer to and from which anions are reversibly dopable and de-dopable. A ratio V1/V0 of a volume V1 of pores with a pore size of 0.2 μm or less to a volume V0 of all pores is 0.40 or more when a pore distribution of the positive electrode is measured using a mercury porosimeter.

Abstract: In a bidirectional switch of a power converter, a first terminal thereof is connected to a connection node between a first switching element and a second switching element. A resonant capacitor is connected between the first terminal of the bidirectional switch and a second DC terminal. A resonant inductor is connected to a second terminal of the bidirectional switch. A regenerative element is connected between the resonant inductor and the second DC terminal. A first control unit controls the first switching element and the second switching element. A second control unit controls the bidirectional switch. A limiter limits the absolute value of a voltage variation rate of a voltage applied between the first and second terminals of the bidirectional switch to a threshold value or less.
