A bidirectional isolated DC-DC converter

2020 IEEE 9th Joint International Information Technology and Artificial Intelligence Conference (ITAIC), 2020
Aiming at the high switching voltage spikes and hard switching phenomena of traditional bidirectional isolated DC-DC converters, a bidirectional isolated DC-DC converter that can achieve zero voltage switching (ZVS) in the full power range is proposed. The two half bridges on the primary side of the converter are both Boost circuits, and the capacitor ...

A Novel High Gain Bidirectional DC-DC Converter

2020 IEEE Industry Applications Society Annual Meeting, 2020
The electric vehicle requires bidirectional DC-DC converter. A high conversion ratio is preferred to interface a low input battery voltage to the high voltage DC and vice-versa. A novel high gain DC to DC bidirectional switched converter is proposed in this paper. The proposed converter uses the interleaved technique to the input side so that the input

Reliability Comparison of Bidirectional Automotive DC/DC Converters

2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017
The energy consumption of modern vehicles has increased rapidly in the last years. Hence, future vehicles require larger batteries and a higher generator power to supply the vehicle loads. For an efficient transport of energy an additional voltage level is introduced, so that dc/dc converters are necessary to couple the different voltage levels ...

A Current-Fed Isolated Bidirectional DC–DC Converter

IEEE Transactions on Power Electronics, 2017
This paper proposes a current-fed isolated bidirectional DC-DC converter (CF-IBDC) which has the advantages of wide input voltage range, low input current ripple, low conduction losses, and soft switching over the full operating range. Compared with conventional CF-IBDCs, the voltage spikes of the low-voltage (LV) side switches in the proposed ...
