| Abstract |
This paper presents a new DC-AC inverter for photovoltaic (PV) and single-phase applications, in
particular for the AC-Module. The benefits associated with this new inverter are a low number of
components and the possibility of an inherent power decoupling.
A novel power-decoupling scheme is also presented. The aim for the power decoupling is to reduce
the amount of capacitance inside the inverter. The decoupling scheme can also be used together with
the boost DC-AC inverter. The decoupling is a must for achieving a good utilization of the PVmodule.
This is hard to achieve with today’s single-stage inverters without using large electrolyticcapacitors.
A large capacitor involves a decreased lifetime, which this solution overcomes. |
