Study of a New Type of DC-DC Converter

Detailed analysis and design of one-cycle-controlled Cuk converter are presented. Based on conventional average state space theory, D-d technique is proposed. The method provides simple algorithm, clear physics conception to study robustness of the system and to find two original approaches to defining the maximal duty ratio limitation. The converter are successfully developed and tested. Experiment result is consistent with mathematical modeling and strongly supports the method of analysis. The device is suitable for different demands of vehicle power supply system.
