要約(日本語): This paper presents an interleaved LLC resonant converter using phase shift modulation. The interleaved PFM LLC resonant converter has difficulty in synchronizing switching instants among phases due to the parameter mismatch of resonant circuits. The parameter mismatch of each phase in LLC resonant circuit causes different gain characteristics at a synchronized switching frequency, which leads to the current unbalance among phases. The current unbalance caused by the parameter mismatch is compensated by PSM in the proposed method.
