| Popis: | In this paper we propose the mode selection strategy of a multi-mode single-stage single-phase inverter and the associated mode selection scheme for double-line-frequency power pulsation decoupling between the input an the output port for PV (photovoltaic) panel applications. Multiple modulation strategies are used along the line cycle to optimize the overall efficiency of the converter. The proposed topology uses several modulations for the inductor current waveform, such that the power handled internally by the elements in the converter is minimized at any time, while performing the output voltage control and power decoupling. The evaluation and selection of the most appropriate modulation in real-time represents a challenge for the control. This work allows to reduce the computational cost of evaluating the decision metric. A mode selection scheme is proposed and validated in a hardware prototype. |
