Abstract
This paper proposes a current-fed two inductor bi-directional DC-DC converter using resonance (CF-TIBCR). The power losses of CF-TIBCR mainly occur in switches, especially the low voltage side switches. To improve the efficiency, the detailed loss analysis of switch and magnetic components is performed from the steady state analysis and operation principles. To verify theoretical loss analysis, it is compared with experiment results using a laboratory prototype converter with 500W. Finally, several method are derived to improve efficiency. © 2015 IEEE.
