Solar high frequency isolation grid-connected inverter
Abstract— In this paper, a new topology for grid-connected solar PV inverter is proposed. The proposed topology employs an LLC resonant converter with high frequency isolation transformer in the DC-DC stage. The DC-DC converter stage is controlled to generate a rectified sine wave voltage and. . ction. This suggested topology comprises two cascaded stages linked by a high-frequency transformer. In the first stage, a new buck–boost inverter with one energy storage is implemented. The buck–boost inverter can convert the PV module's output voltage to a high-frequency square wav (HFSWV) and. . This paper proposes a new topology of PV grid-tie applications. The full system consists of two-stages, high-frequency boost inverter cascaded by rectifier–inverter system. A single-phase high-frequency transformer is used to link both stages and provide galvanic. . Isolation type solar grid connected inverters can be divided into power frequency isolation type and high-frequency isolation type based on the operating frequency of the transformer. The structure of power frequency isolation type solar grid connected inverters is shown in Figure 1. [PDF Version]
