| Outline of Final Research Achievements |
The research subject deals with a single-stage high frequency-link single-phase ac-dc converter. Based on the three-phase topologies that was developed in the former steps of research period, the boost ac chopper and full-bridge inverter integrated ac-dc converter is explored for a single-phase utility frequency to high frequency converter, featuring the single-stage power conversion via the non-smoothed dc-link and high frequency transformer as well as the power factor correction in continuous conduction mode (CCM) in the ac line current. Effectiveness of the single-phase ac-dc converter is investigated by simulation analysis, whereby the 60Hz-50kHz ac power conversion is confirmed under the principle of single-stage operation and PFC in CCM attains with accommodation for the world-wide standard. The experimental verification will be a future work of the subject.
