Abstract: In the field of electrical solar power conversion efficiency is the most important topic. In common single-phase inverter applications the current of the solar array shows a remarkable ripple. This entails two significant disadvantages: Reduced over all efficiency due to dynamic maximum power point mismatch and reduced lifetime of the panels due to additional component stress. Furthermore in environments with several solar strings operating in parallel to reach the goal of a very close MPP operation, a distributed current source arrangement has to be chosen. The proposed topology discussed in this paper uses a separated active filter to fulfill the given requirements: Minimized input current ripple of the cells, string-optimized maximum power point tracking and optimal power quality of the supplying grid. The topology presented in this paper shows a remarkable improvement of the over-all efficiency as well as a significantly enhanced EMC. Consequently, it is well s!
uited for solar power inverter applications.
