A Novel, Ultra-Compact, High-Efficiency Power Conditioning System for Integration into Roof-Top Photovoltaic Modules

本建议试图设计一个有效的电力调节系统的光伏互连到住宅。本设计是基于DC-DC变换器和逆变器的拓扑结构，这种拓扑结构本身并不是一种新的方案，它已经在很多光伏系统中得到了应用。 此外，所提出的方案被设计为使用从MPPT算法（假设安装在基于微计算机的系统中）导出的最大功率点（电压或电流）。 实际上，基于计算机的最大功率跟踪器的高成本是MMPT在小型光伏项目中不被广泛接受的主要原因。 光伏市场和应用还没有证明采用MPT的好处是从光伏电池中提取的功率比MPT的初始成本多一点。 在小尺寸PV应用中，高度寻求更经济的功率跟踪器。 此外，如果DC-DC转换器被包括在所提出的方案中，DC-DC控制方案，例如电流控制，是否可以适应MPPT控制？

This proposal attempts to design an efficient power conditioning system for PV interconnection to a residence. The design is based on DC-DC converter and Inverter topology, and this topology itself is not a new scheme; it has been used in many cases of PV systems. Also, the proposed scheme is designed to use the maximum power point (Voltage or current) derived from a MPPT algorithm (which assumed to be installed in a microcomputer based system). Actually, the main reason that the MMPT is not well accepted in a small PV project is that the high-cost of the computer based maximum power tracker. The PV market and application have yet to justify the adoption of MPT in terms of the benefit of just a little more power drawn from the PV cells against the initial costs of the MPT. In a small size PV application, more economical power tracker is highly sought. In addition, if the DC-DC converter is included in the proposed scheme, could the DC-DC control scheme, such as current control, accommodate the MPPT control?
