Tubes à rayons X Résumé : Employing a new rectifier circuit, i.e., a novel current-fed boost converter with ripple reduction, is proposed in this paper. It features high conversion ratio with smaller transformer turn ratio, recovery of transformer secondary leakage energy, low voltage stress on the rectifier diodes, and lower input- and output-current ripples with minimum component count. Therefore, high efficiency and power density can be achieved under high-frequency operation. Moreover, the new rectifier circuit can be applied to all current-fed power topologies for high-voltage conversion applications, such as fuel-cell-powered systems. The operating principle, theoretical analysis, and design considerations are presented. To demonstrate its feasibility, a 150-kHz, 16-22-V-input, and 200-V/400-W-output converter is implemented and tested.
