An approach for the high power density rectifier has been investigated to realize future highly efficient DC power distribution. The combination of ISOP (Input Series and Output Parallel)-IPOS (Input Parallel and Output Series) isolated DC-DC converter for the DC transformer and the three-phase AC-DC PWM converter using novel power devices as SiC (Silicon Carbide) transistor for the output voltage regulation has been applied. A prototype of 384 V-12 V 2.4 kW isolated DC-DC converter has been fabricated and the efficiency of 98% has been verified experimentally. The breadboard of AC 200 V-DC 384 V 2.4 kW converter has been also fabricated. The efficiency of 97% has been measured in the experiment and the potential to achieve 98% has been shown through the design consideration. The proposed methodology can be utilized for several levels of DC distribution (i.e. 12 V, 48 V, 384 V) keeping the power density and the conversion efficiency of the rectifier and contributes to the realization of highly efficient DC power distribution and future low carbonated society.
