Document Type and Number:
WIPO Patent Application WO/2018/169136
Kind Code:
A1
Abstract:
The present invention relates to a 3-level bidirectional DC-DC converter comprising: a first voltage part for generating a low voltage; a second voltage part for generating a high voltage that is higher than the low voltage; a 3-level switch part including four switches connected in series and at least one inductor, and generating a 3-level voltage through a selective switching operation of each switch; a first resonance part including an LC resonance element, and performing series resonance while the first switch or the second switch connected in series among the four switches is conducted so as to apply the resonance current to the conducted switch; and a second resonance part including an LC resonance element, and performing series resonance while the third switch or the fourth switch connected in series among the four switches is conducted so as to apply the resonance current to the conducted switch.
