| Abstract: | In this paper, a two-stage (Boost and invert) application specific inverter is designed and developed based on the practical application of solar pumping systems. By discussing and comparing the operating characteristics of all kinds of control modes via systematic experiments and the developed product prototype of the inverter, the final optimal scheme of this product is determined. Furthermore, the comprehensive comparisons with the single-stage inverter for solar pumping systems are made, and the optimum... |
