Patent number: 6078163Abstract: An inductor (L), capacitor (C) and alternator (OSC) are connected in series to the positive and negative poles of a battery (15). The temperature of the battery (15) is increased by causing the alternator (OSC) to generate an alternating current having the resonance frequency of the inductor (L) and capacitor (C). The alternating current is consumed by the internal resistance of the battery (15) due to the resonance of the inductor (L) and capacitor (C), and the temperature of the battery (15) therefore rises due to the heat thereby generated in the battery. In this way, the temperature of the battery (15) can be effectively increased with minimum power consumption.Type: GrantFiled: May 14, 1999Date of Patent: June 20, 2000Assignee: Nissan Motor Co., Ltd.Inventors: Hideaki Horie, Toyoaki Nakagawa, Mikio Kawai, Yuji Tanjo, Takaaki Abe, Ken Iwai

Patent number: 5768117Abstract: The invention relates to a power supply system having plural converters connected in parallel. The current of each of the plural converters is detected and each of the converters is controlled so as to match each of the converters to a maximum current value from among the detected current values. In the parallel converters, when one or more converter fails, having an output current of zero, the remaining converters are each partially charged equally to maintain the load current. Since a common bus is arranged between plural converters and plural loads, it is possible to carry out a redundant operation having a high reliability. Since a stable output can be obtained without being affected by the failed converter, a power supply system having the redundancy and the high reliability can be attained.Type: GrantFiled: December 27, 1994Date of Patent: June 16, 1998Assignee: Hitachi, Ltd.Inventors: Tadashi Takahashi, Kenichi Onda, Akihiko Kanouda, Masayoshi Sato, Hideaki Horie, Katsunori Hayashi

An a.c. power is supplied via the relay contacts to each switching power supply. The relay driving time set in the rush current limiter circuit is different for each switching power supply.Type: GrantFiled: October 17, 1995Date of Patent: June 10, 1997Assignee: Hitachi, Ltd.Inventors: Katsunori Hayashi, Akihiko Kanouda, Tadashi Takahashi, Hideaki Horie, Kenichi Onda, Yasuo Abe, Masayoshi Sato

Patent number: 5559682Abstract: A diode, a condenser and a switching element are connected to a primary winding of a flat type transformer such as a wire type transformer. A citation energy discharged during an off-condition of the switching element, namely a reset period of the transformer, is accumulated in the condenser. An output voltage is obtained from the condenser. Two system direct current voltage output can be obtained from one transformer. Since the two system direct current voltage output can be obtained from the transformer having a pair of a primary winding and a secondary winding, the volume and the weight of the transformer can be reduced and the compact and the slim of the machine apparatus being mounted can be contributed. Making the small winding ratio of the transformer, the copper loss of the transformer can be reduced. By using MOS synchronous rectification, the loss in the circuit can be reduced. It is unnecessary to select highly the switching frequency.Type: GrantFiled: January 6, 1994Date of Patent: September 24, 1996Assignee: Hitachi, Ltd.Inventors: Akihiko Kanouda, Tadashi Takahashi, Hideaki Horie, Kenichi Onda, Syuya Hagiwara
