Abstract

A worldwide concern for future access to affordable, sustainable energy is driving the development of more efficient solar power generation. In any photovoltaic (PV)-based system, the inverter is a critical component responsible for current control between the PV module, battery, loads and power grid. Inverters, which convert direct to alternating current, can be designed to be used with different voltage ranges and topologies for varying applications, and they can also be designed with or without transformers. Besides DC/AC conversion, inverters provide additional functions such as maximizing power, battery charging and protecting the circuit. All of these functions require optimized intelligent control that can occur in real time or near-real time; and the wide variations in application and operational requirements mean that the system control has to be highly flexible. Digital signal processor (DSP)-based controllers, such as the Texas Instruments TMS320C2000 family of controllers, provide the high level of computational performance and programming flexibility needed for the real-time signal processing in solar power inverters. Highly integrated digital signal controllers help inverter manufacturers create more efficient, more cost-effective products that can support the growing demand for solar energy in upcoming years

数字信号控制器提高太阳能逆变器的效率

全世界都在关注未来能否获得负担得起的可持续能源，这推动了更高效太阳能发电的发展。在任何基于光伏(PV)的系统中，逆变器是负责光伏组件、电池、负载和电网之间电流控制的关键部件。逆变器可以将直流电转换为交流电，可以设计成用于不同的电压范围和拓扑结构，用于不同的应用，也可以设计成带或不带变压器。除了DC/AC转换，逆变器提供额外的功能，如最大限度地提高功率，电池充电和保护电路。所有这些功能都需要优化的智能控制，可以实时或近实时地发生;应用和操作要求的广泛变化意味着系统控制必须具有高度的灵活性。基于数字信号处理器(DSP)的控制器，如德州仪器TMS320C2000系列控制器，为太阳能逆变器的实时信号处理提供了高水平的计算性能和编程灵活性。高度集成的数字信号控制器帮助逆变器制造商创造更高效、更具成本效益的产品，以支持未来几年对太阳能日益增长的需求
