A New Modulation Method Applying Optimal Duty Cycle and Phase Shift for Bidirectional Isolated Three-Phase AC/DC Converter Based on Matrix Converter

Koji Shigeuchi Jin Xu Noboru Shimosato Yukihiko Sato

2018 INTERNATIONAL POWER ELECTRONICS CONFERENCE (IPEC-NIIGATA 2018 -ECCE ASIA) 3514-3521 2018年 [査読有り]

This paper presents a new modulation method for high-frequency link bidirectional three-phase AC/DC converter based on matrix converter. Since the matrix converter does not have electrolytic capacitor, it achieves high power density and long lifet...

Decoupling Control Method for Eliminating DC Bias Flux of High Frequency Transformer in a Bidirectional Isolated AC/DC Converter

Kensuke Sakuma Koji Shigeuchi Jin Xu Noboru Shimosato Yukihiko Sato

2018 INTERNATIONAL POWER ELECTRONICS CONFERENCE (IPEC-NIIGATA 2018 -ECCE ASIA) 3522-3527 2018年 [査読有り]

This paper proposes a new method of eliminating DC bias flux of high frequency transformer in a bidirectional isolated AC/DC converter. The converter treated in this paper has a matrix converter and a full-bridge converter in primary and secondary...

Novel High-Voltage High-Power DC-DC Converter for Offshore Wind Farms

Takaharu Ishibashi Takushi Jimichi Yukihiko Sato

2018 20TH EUROPEAN CONFERENCE ON POWER ELECTRONICS AND APPLICATIONS (EPE'18 ECCE EUROPE) 2018年 [査読有り]

This paper deals with offshore wind system with DC collector grid, in which a high-voltage (HV) DCDC converter is utilized between the DC collector gird and HVDC transmission line. This study is focused on the circuit configuration of the HV DC-DC...

Rectification Methods to Increase Harvested Energy in Vibration Generation Using Piezoelectric Elements

Toru Tanaka Tomoya Aonuma Kenji Natori Yukihiko Sato

ELECTRICAL ENGINEERING IN JAPAN 199(3) 68-79 2017年5月 [査読有り]

We studied vibration power generation using piezoelectric elements in order to determine effective rectification methods to increase harvested energy from vibration power generation systems. First, we experimentally clarified the output characteri...

Total Volume Reduction of Passive Components in Grid-Connected Converters by Introducing Flying Capacitor Multilevel Topology

Sae Mochidate Yukihiko Sato Tomotake Ito Hidemine Obara

2017 IEEE 3RD INTERNATIONAL FUTURE ENERGY ELECTRONICS CONFERENCE AND ECCE ASIA (IFEEC 2017-ECCE ASIA) 551-555 2017年 [査読有り]

Grid-connected voltage source converters are widely used in various applications. In these Grid-connected converters, volume of the passive components such as AC side inductors and harmonic filters becomes sometimes a practical problem. As a solut...
