This paper discusses a Dual Active Bridge (DAB) DC-DC converter utilizing to three-level flying capacitor topology for a battery conversion system. With applying to a multi-level topology, the voltage stress is reduced in all switches. In addition, the low order harmonic components are reduced due to five-level waveform. In a two-level DAB converter, the efficiency becomes low when the input voltage is not closed to the nominal voltage. In order to improve the efficiency at the input voltage… CONTINUE READING
