Abstract |
This paper proposes the coupled inductor rectifier of Three-Level DC/DC converter and studies about rectification methods comparison of the Three-Level converter. The CICDR-TL(Coupled Inductor Current Doubler Rectifier Three-Level) converter achieve ZVS(Zero Voltage Switching) for the switches in a wide load range. CDR(Current Doubler Rectifier) and CICDR Three-Level converter has small voltage and current ripple. Advantages and disadvantages of topology compared to the rectifier of bridge, center-tap, CDR, and CICDR are discussed. Experimental evaluation results obtained on a 27[V], 60[A] DC/DC TL converter prototype for the 1.8[kW], 40[kHz] IGBT based experimental circuit. |
