Optimal Design Considerations of a Bus Converter for On-Board Distributed Power Systems
Abe, Seiya,Hirokawa, Masahiko,Shoyama, Masahito,Ninomiya, Tamotsu The Korean Institute of Power Electronics 2009 JOURNAL OF POWER ELECTRONICS Vol.9 No.3
The power supply systems, which require low-voltage / high-current output has been changing from the conventional centralized power system to a distributed power system. The distributed power system consists of a bus converter and POL. The most important factor is the system stability in bus architecture design. The overlap between the output impedance of a bus converter input impedance of POL causes system instability and has been an actual problem. By increasing the bus capacitor, the system stability can be easily improved. However, due to limited space on the system board, the increasing of bus capacitors is impractical. An urgent solution of this issue is strongly desired. This paper presents the output impedance design for on-board distributed power system by means of three control schemes of a bus converter. The output impedance peak of the bus converter and the input impedance of the POL are analyzed and then conformed experimentally for stability criterion. Furthermore, the design process of each control schemes for system stability is proposed.

The power supply system which requires the low-voltage / high-current output has been changing from conventional centralized power system to distributed power system. The distributed power system consists of bus converter and POL. The most important factor is the system stability in bus architecture design. The overlap between the output impedance of bus converter and input impedance of POL causes system instability, and it has been an actual problem. Increasing the bus capacitor, system stability can be reduced easily. However, due to the limited space on the system board, increasing of bus capacitors is impractical. The urgent solution of the issue is desired strongly. This paper presents the output impedance design for on-board distributed power system by means of three control schemes of bus converter. The output impedance peak of the bus converter and the input impedance of the POL are analyzed, and it is conformed by experimentally for stability criterion. Furthermore, the design process of each control schemes for system stability is proposed.
Universal Design with Robots for the Wide Use of Robots
Nobuto Matsuhira,Junko Hirokawa,Hideki Ogawa,Tatsuya Wada 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
Home use robots and service robots have been expected for the society of the aging and the falling birthrate. However, a lot of disturbance avoiding the robot’ activities exists in such an environment. Universal Design with Robots (UDRob<SUP>TM</SUP>) has been proposed to cope with these problems in our daily life environment using the concept of universal design. Here, interface designs for mobility, handling, and image processing are especially considered in the concept. Conceptual design of the robot system based on UDRob<SUP>TM</SUP> and the interaction design has been shown here.
