逆变器作为光伏阵列和电网接口的主要设备，它的性能决定着整个光伏发电系统的性能。为了将光伏阵列产生的电能最大限度地馈入电网，并提高其运行的稳定度、可靠性和精确度，必须对并网逆变器的主电路拓扑选择、滤波器参数设计及其控制策略选取等进行深入研究。 论文首先分析了光伏发电的国内外发展现状和应用前景，对光伏并网发电系统的种类、结构和并网标准进行了综述。针对众多适用于光伏并网的逆变器拓扑进行了详细的比较分析，最终确定了一台单相满载功率1kW、并网电压220V的逆变器拓扑及其主电路参数，对其输出滤波器参数进行设计，并对其进行了幅频特性分析。 其次，详细分析和研究逆变器的并网控制策略，确定了在独立工作模式下的瞬时电压控制策略和在并网工作模式下的瞬时电流控制策略。根据选定的控制策略分别对其控制系统进行了建模和闭环参数设计，并利用Sabet软件进行系统仿真，验证了系统建模和设计的正确性。 接着，在分析光伏阵列特性的基础上，总结和比较了常用的几种MPPT（Maximum Power Point Tracking）控制方法，通过扰动观测法对并网逆变器输出电流的控制，实现了光伏阵列的MPPT，并给出了设计方案和实验验证。 最后，根据以上分析结果，研制了一台基于DSP控制的光伏并网逆变器的试验样机，并详述了其软硬件的设计方案，给出了相关实验结果。

Abstract: There are many things to consider when designing a power supply for a field-programmablegate array (FPGA). These include (but are not limited to) the high number of voltage rails, and thediffering requirements for both sequencing/Tracking and the voltage ripple limits. This application noteexplains these and other power-supply considerations that an engineer must think through whendesigning a power supply for an FPGA.

Multiple-voltage electronics systems often requirecomplex supply voltage Tracking or sequencing, whichif not met, can result in system faults or even permanentfailures in the fi eld. The design diffi culties in meetingthese requirements are often compounded in distributedpowerarchitectures where point-of-load (POL) DC/DCconverters or linear regulators are scattered across PCboard space, sometimes on different board planes. Theproblem is that power supply circuitry is often the lastcircuitry to be designed into the board, and it must beshoehorned into whatever little board real estate is left.Often, a simple, drop-in, fl exible solution is needed tomeet these requirements.

为解决直流逆变交流的问题，有效地利用能源，让电源输出最大功率，设计了高性能的基于IR2101最大功率跟踪逆变器，并以SPMC75F2413A单片机作为主控制器。高电压、高速功率的MOSFET或IGBT驱动器IR2101采用高度集成的电平转换技术，同时上管采用外部自举电容上电，能够稳定高效地驱动MOS管。该逆变器可以实现DC/AC的转换，最大功率点的跟踪等功能。实际测试结果表明，该逆变器系统具有跟踪能力强，稳定性高，反应灵敏等特点，该逆变器不仅可应用于普通的电源逆变系统，而且可应用于光伏并网发电的逆变系统，具有广泛的市场前景。 Abstract: To solve the problem of DC-AC inverter， and to utilize solar energy more efficiently， the design of maximum power point Tracking inverter based on IR2101 was achieved with a high-performance， which can make the system output power maximum. SPMC75F2413A was adopted as main controller. IR2101 is a high voltage， high speed power MOSFET and IGBT driver. It adopted highly integrated voltage level transforming technology， and an external bootstrap capacitor was used， which could drive MOS tube efficiently and stably. Many functions are achieved in the system， such as DC/AC conversion， maximun power point Tracking， etc. The actual test result shows that the inverter system has characteristics of strong Tracking ability， high stability and reacting quickly. The design can not only be used in ordinary power inverter system， but also be used in photovoltaic power inverter system. The design has certain marketing prospects
