    Abstract

    :

    Module integrated converters (MICs) have been under rapid development for single-phase grid-tied photovoltaic applications. The capacitive energy storage implementation for the double-line-frequency power variation represents a differentiating factor among existing designs. This project introduces a new topology that places the energy storage block in a series-connected path with the line interface block. This design provides independent control over the capacitor voltage, soft-switching for all semiconductor devices, and the full four-quadrant operation with the grid. The proposed approach is analysed and experimentally demonstrated. Module integrated converters (MICs) have been under rapid development for single-phase grid-tied photovoltaic applications. This project introduces a new topology that used to perform in unity power factor operation.
