Patent number: 11881788Abstract: In a DC/DC converter, in first power transmission in which power is transmitted from a first DC power source to a second DC power source, on/off drive of a positive electrode-side switching element and a negative electrode-side switching element is stopped in a third bridge circuit on the power-receiving side. When a power transmission amount by the first power transmission is smaller than a first reference value, a control circuit lowers the switching frequency of the switching elements of a first bridge circuit and a second bridge circuit on the power-transmitting side and a fourth bridge circuit on the power-receiving side, compared with when the power transmission amount is equal to or greater than the first reference value.Type: GrantFiled: December 16, 2019Date of Patent: January 23, 2024Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Yuki Itogawa, Yu Kawai, Takeshi Amimoto, Yusuke Higaki, Tomoaki Kimura

Patent number: 11791712Abstract: A power conversion device converts a direct-current power on the DC side of the power conversion device to an alternating-current power by an inverter circuit having a plurality of semiconductor switching elements, and outputs the AC power from the AC side of the power conversion device. A current detector detects a reactor current output from the inverter circuit. As overcurrent detector detects overcurrent in a control mode in which the reactor current is caused to follow a reactor current command value, control circuit starts an overcurrent mode in which a time period where the reactor current monotonically decreases is provided. In the overcurrent mode, whether to switch the overcurrent mode to the normal control mode is determined based on the reactor current or in accordance with a timing corresponding to a zero-cross point of a voltage or current on the AC side.Type: GrantFiled: January 9, 2019Date of Patent: October 17, 2023Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Takeshi Amimoto, Kikuo Izumi, Tatsuya Okuda, Tomoaki Kimura
