| Outline of Final Research Achievements |
This research has dealt with a high-efficiency power conversion circuits suitable for inductive power transfer (IPT) without a bulky smoothing dc-link filter. In the first stage of the research, the new type of utility frequency (UF)- high frequency (HF) ac -ac power converter with voltage boost and power factor correction (PFC) has been developed, and evaluated in experiment. The high-efficiency over 95% has been demonstrated in the 3kW prototype circuit due to the smoothing dc-link capacitor-less circuit topology.
The second stage of the research has been dedicated for development and evaluation of HFAC (DC)-DC power converter in contact-less power process for IPT. The high-efficiency power conversion over 95% has been attained in the 2.5kW IPT prototype due to the series-series resonant circuit configuration.
The total power conversion efficiency can be expected about 90% by utilizing the newly-devopoed two power converters applicable for IPT.
