Abstract

In the applications of multi-source system (like these cases for solar cells, wind generation, fuel cells, dc sources coming from ac sources and general rechargeable cells, etc.), the converter is the most important part. The function of the system is influenced directly by the performance of converter. Therefore, a high performance converter is the key to success. One of the applications is the photovoltaic energy conversion system. After comparison of the merits and weakness between the common photovoltaic energy conversion systems, a new soft switching converter suitable to the multi-source applications is presented. Aside from the capability of making the maximum power point tracking, the main switch also has the capability of zero voltage transition, which could minimize the loss caused by the transition of the switch. Also, the energy transformed from the switch could be transferred to the battery and recharge the battery. The battery could also be recharged and discharged to achieve the energy balance of system. Although the photovoltaic energy conversion system is taken as an example here, however the new soft switching circuit can be also used to the other multi-source applications including wind generation, fuel cells, dc sources and rechargeable cells, etc..
