要約(英語): This paper proposes a 2.5MHz high-frequency output inverter based on a frequency multiplying technique with a multi-core transformer using Mn-Zn ferrite materials. The upper limit of the operation frequency for these materials is lower than the output frequency of 2.5MHz. First, the operation principle of the proposed circuit is explained. Second, a difficulty of using Mn-Zn for transformers at the frequency of 2.5MHz is discussed. Third, a numerical analysis shows that the proposed circuit can output the frequency over the upper limit of the operation frequency of Mn-Zn ferrite. Finally, through continuous operation, where the proposed circuit outputs approximately 650W, it is experimentally confirmed that Mn-Zn ferrite can be used without large iron loss at the output frequency of 2.5MHz. Thus, the proposed circuit can overcome the difficulty of using Mn-Zn for transformers at the frequency of 2.5MHz.
