Patent number: 8456035Abstract: Main arrays (MA1-MAm) of solar cells (2) are provided so as to correspond to shunt circuits (SM1-SMm), respectively. Charge arrays (CA1-CAn) are provided so as to correspond to shunt circuits (SC1-SCn) and charging circuits (CH1-CHn), respectively. Each shut circuit operates independently from other shunt circuits, and each charging circuit operates independently from other charging circuits.Type: GrantFiled: November 6, 2008Date of Patent: June 4, 2013Assignees: NEC TOSHIBA Space Systems, Ltd., Japan Aerospace Exploration AgencyInventors: Teiji Yoshida, Tomotake Gondai, Koichi Kibe, Hiroaki Kusawake, Hitoshi Naito, Go Segami

Patent number: 7701182Abstract: Disclosed is a low noise, non-isolated DC-DC converter for providing a non-inverted (i.e., the same polarity as an input voltage) output voltage of any desired voltage by stepping-up/down the input voltage. It comprises an input coil L1, an input capacitor C1 and a second intermediate coil Lm2 connected in series between both ends of the input voltage source, an output coil L2, an output capacitor C2 and a first intermediate coil Lm1 connected in series between both ends of a load Ro, a switching device S connected between a node a of the L1 and the C1 and a node b of the C2 and the Lm1, and a diode D connected between a node d of the C1 and the Lm2 and a node c of the C2 and the L2.Type: GrantFiled: June 27, 2008Date of Patent: April 20, 2010Assignee: NEC Toshiba Space Systems, Ltd.Inventor: Teiji Yoshida

Patent number: 7683590Abstract: A step-down switching DC-DC converter may include an input coil on the input side, an output coil on the output side, a switch, an output capacitor, a first series circuit connected between a connection point on which the input coil and the switch are connected each other and a negative pole of a power source, and a second series circuit connected between a connection point on which the output coil and the switch are connected to each other and the negative pole of the power source. A connection point between a first intermediate capacitor and the first intermediate coil is connected to a connection point between a second intermediate capacitor and the switch via a switching device cooperating with the switch. The input coil and the first intermediate coil are electromagnetically coupled with each other. The output coil and the second intermediate coil are electromagnetically coupled with each other.Type: GrantFiled: March 13, 2009Date of Patent: March 23, 2010Assignee: NEC CorporationInventor: Teiji Yoshida
