ANOlog_TMS320F28335
本装置采用单相桥式DC-AC逆变电路结构，以TI公司的浮点数字信号控制器TMS320F28335 DSP为控制电路核心，采用规则采样法和DSP片内ePWM模块功能实现SPWM波。最大功率点跟踪（MPPT）采用了恒压跟踪法（CVT法）来实现，并用软件锁相环进行系统的同频、同相控制，控制灵活简单。采用DSP片内12位A/D对各模拟信号进行采集检测，简化了系统设计和成本。本装置具有良好的数字显示功能，采用CPLD自行设计驱动的4.3’’彩色液晶TFT LCD非常直观地完成了输出信号波形、频谱特性的在线实时显示，以及输入电压、电流、功率，输出电压、电流、功率，效率，频率，相位差，失真度参数的正确显示。本装置具有开机自检、输入电压欠压及输出过流保护，在过流、欠压故障排除后能自动恢复。(This device single-phase bridge type DC-AC inverter circuit structure, TI company of floating in digital signal controller TMS320F28335 DSP as the control circuit, the core rules sampling method and DSP piece ePWM module function realization within SPWM wave. The maximum power point tracking (MPPT) used the constant pressure tracking method (CVT method) to realize the software, and phase lock loop to carry on the system the same frequency, phase control, control with flexible simple. By using DSP piece of 12 within the A/D of each simulation signal acquisition detection, simplified system design and cost. This device has a good digital display function, use CPLD to design the driver 4.3 " TFT LCD color LCD very intuitive to finish the output signal waveform and spectrum characteristics of online real-time display, and the input voltage, current, power, the output voltage, current, power, efficiency, frequency, phase difference, the distortion degree of parameters display properly.

Code(6)
As the figure above illustrates, a phase accumulator compares the sample clock and desired frequency to increment a phase register. Again, the fundamental idea is that we can generate signals with precise frequencies by generating an appropriate sample based on the phase of that frequency at any point in time. In addition, by representing our waveform with 214 (16,384) points, we are able to represent exactly 16,384 phase increments with our lookup table.
