Solar array inverter with maximum power tracking

摘要: An inverter for use in connecting a DC power source to the utility grid includes single DC-DC conversion stage, maximum (source) tracking, and current control based on feed-forward compensation as function of an input commanding voltage, rectified line either scaled squared inverse or RMS voltage. Various embodiments also include over-voltage, over-current, under-voltage, over-temperature protection, stand-by battery with its management control, while others adapt multiple-channel front-end distributed system tracking serve downstream controllers, emergency auxiliary loads, alternative feedback systems providing in-phase output respect voltage absorbing available from minimally utilizing maximal reliability.
