ASM Code for calculator using AVR

可再生能源光伏发电和风力发电是重要的能源，而外界环境的影响也要分析，提出的方案很好地适应了这种变化。(The integration of renewable resources such as solar and wind energy is becoming increasingly attractive. This is being used widely for bstitution of oil-produced energy and will help to minimize atmospheric degradation.)

：介绍了一种基于数字信号处理器（DSP）的移相调频（Phase-Shifted and Frequency-Varied，PSFV）PWM控制 逆变电源，给出了主电路拓扑结构，分析了其控制原理并设计了其控制程序流程图。新颖的PSFV 控制能够实现输出 电压90％的调整率，输出电流波动小于单纯移相调功PWM方式，并在轻载时保持连续。功率开关器件零电压零电流 通断（Zero-Voltage-Zero-Current Switching，ZVZCS）软开关的实现，有利于进一步提高开关频率和降低开关损耗。采用 高性能的专用DSP 芯片TMS320F2812 实现了系统的数字控制，满足了系统控制的灵活性和实时性，减小了系统的 体积和生产成本。仿真分析和实验结果证明了此控制模式的可行性与合理性。()

本文介绍了一种采用Altera 公司的FFT MegaCore 实现快速傅里叶变换的方法，该方法非常简单，能进一层次简化开发的流程，缩短工程开发周期，节约成本，因此在实际工程中是一种很好的应用。(This paper describes a use of Altera s FFT MegaCore fast Fourier transform method, the method is very simple and can develop into a hierarchy to simplify processes, shorten the project development cycle, cost savings, and therefore is a practical engineering good application.)
