Publication number: 20240088694Abstract: An electrical charging apparatus working to electrically charge an electrical storage device includes an electrical power converter and a controller. The electrical power converter converts an alternating-current input voltage into a direct-current voltage and outputs it to the electrical storage device. The controller works to control the electrical power converter to pulsate the charging current supplied from the electrical power converter to the electrical storage device. The controller also controls the electrical power converter to set a pulsation frequency of the charging current to an integral multiple of the frequency of the input voltage and also to bring a phase difference between a zero-crossing time of the input voltage and a time when the charging current is minimized to be smaller than or equal to one-eighth of one cycle of the input voltage.Type: ApplicationFiled: November 22, 2023Publication date: March 14, 2024Applicant: DENSO CORPORATIONInventors: Kazuhiro SHIRAKAWA, Keiya Tani, Shunichi Kubo

Publication number: 20240088813Abstract: An inverter in a power conversion apparatus has a series connection body of upper- and lower-arm switches. The series connection body connects in parallel to a series connection body of first and second power storage units. A rotating electric machine has a winding that is electrically connected to the inverter. A neutral-point wiring electrically connects a negative electrode side of the first power storage unit and a positive electrode side of the second power storage unit, and a neutral point of the winding. A control unit performs switching control of the upper- and lower-arm switches such that a current flows between the first power storage unit and the second power storage unit through the inverter, the winding, and the neutral-point wiring. A case houses at least the inverter and provides a shield function. At least a portion of the neutral-point wiring is housed inside the case.Type: ApplicationFiled: November 13, 2023Publication date: March 14, 2024Applicant: DENSO CORPORATIONInventors: Syusei NISHIMURA, Kazuhiro Shirakawa
