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 overall 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.
