| Abstract: | A novel Cuk converter using soft switching and magnetics-integration technology is proposed in this paper. The converter achieves zero voltage transition （ZVT） and eliminates the ripple current through both input and output inductors, therefore low loss, low noise, low EMI, high efficiency and high power density of the converter are easily achieved. The topology configuration, operating principle, characteristics and parameter designing of the converter are also presented. In the end, it shows the simulation of the proposed converter, and the simulation results verify the academic analysis. |
