High Efficient Topologies for Next Generation Solar Inverter

摘要

Efficiency is becoming increasingly important in power electronics. In many applications, developments are driven by the initiatives for reduced energy consumption. The technology leaders are inverter applications in the solar market, since in this sector higher efficiency leads to a direct payback. The maximum efficiency target introduces new requirements for the electronic topologies and the power electronics components. Examples of new 1～ and 3～ solar inverter topologies are presented. New ideas for cos(Phi) compensation and high efficient bi-directional inverter/converter options are discussed.
