Nevertheless, hybrid vehicles are not a mass product up to now. Although the life cycle costs of the hybrid cars are usually smaller than the costs for comparable fuel vehicles, the main purchase criteria for vehicles are still the acquisition costs, leading to a preference for conventional fuel cars. So as to increase the number of hybrid vehicles, the production costs have to be lowered. In hybrid vehicles, the energy distribution system causes a significant share of volume and costs. One part of this system is the dc-dc converter that transfers power between the low- and high-voltage buses. In order to reduce the costs and the volume of this converter, two new concepts for integrating the dc-dc converter functionality into the traction drive system have been presented in [1]. This paper will present different switching strategies to improve the efficiency of the total system. Starting from the phase-shift modulation known from the conventional Dual Active Bridge, the switching instants are optimized regarding efficiency to obtain the optimal modulation. In addition, a concept with multiple switching during the inverter's switching period is analyzed as well as a slightly modified system, where one leg of the dc-dc converter is implemented as a three-level switch. These four switching strategies are analyzed and compared. In addition, measurement results are shown to verify the calculations.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124345521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The leakage inductance of the coupled inductors can be employed to control the diode current falling rate and to alleviate the diode reverse-recovery problem. Then, some soft switching solutions are realized by the coupled inductor to reduce the switching losses. Furthermore, the coupled inductor can be operated in transformer mode to avoid the extreme duty cycle and to reduce the current ripple in high step-up or step-down conversion. However, the leakage inductance of the coupled inductors may induce high voltage spikes, which will increase the switch voltage stress, result in serious EMI noise and reduce the system efficiency. Even, it will break down the circuit. In one word, the coupled inductor is a two-side sword, which we should consider carefully. The applications of the coupled inductor in DC/DC converters are summarized and classified in this paper. A systematic discussion is given to focus on the performances of the coupled inductor in DC/DC converters. This paper would like to provide a useful framework and point of reference for future applications of the coupled inductor in DC/DC circuits.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123955935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
