三相光伏并网逆变器SVPWM电流控制技术研究(Three-phase photovoltaic grid-connected inverter SVPWM current control technology)

本系统以单片机AT89C52为核心,以数模转换器DAC0832实现方波、正弦波、三角波、锯齿波波形的输出，实现信号发生器的简易功能。(This system with single chip microcomputer AT89C52 as the core, with digital to analog converter DAC0832 achieve square wave, sine wave, triangle wave, sawtooth wave form output, realize the simple function of the signal generator.)

在MSP430单片机上使用PS2鼠标的驱动程序。(The MSP430 MCU PS2 mouse driver.)

测试环境当前温度，用DS18b20传感器显示在lcd1602上(turnover temperature)

说明：  风力摆是一种通过风机作为唯一动力驱动的装置,深入研究该系统对空间飞行器、四旋翼无人机的运动状态和卫星姿态控制具有重大意义。(Wind pendulum is a device driven by wind turbine as the only power. It is of great significance to study the motion state of space vehicle, quad-rotor UAV and satellite attitude control.)

复旦微FM1702读卡芯片底层驱动程序，在GCC环境下编译通过，非常好用(FM1702hardware driver)

说明：  demo1forbaseboard，芯片板的例程1，按键控制led灯的亮灭(Demo1forbaseboard,routine 1 of chip board,key control LED light on and off)

说明：  stm32f103芯片驱动SX1278，小型RTOS，处理SX1278信号，空中唤醒(STM32F103 chip drives sx1278, small RTOS, processes sx1278 signal, wakes up in the air)

逆变器PQ和V/F控制，PSCAD模型，掌握分布式电源这两种控制很有用。(PQ and V/F control inverter, PSCAD model, master the distributed power supply this two kinds of control is very useful.)

说明：  工程教育中级练习题1：按一下K1键，LED以10Hz频率闪烁，屏幕上画出红圈，跟着闪，放开后保持该频率闪烁；长按K1键超过3秒，LED以5Hz频率闪烁，屏幕上画出红圈，跟着闪，放开后保持该频率闪烁；按一下K2键，LED熄灭；按一下K2键，LED常亮。(Secondary Exercise Question 1 in Engineering Education: Press the K1 key, the LED flickers at 10Hz frequency, draw a red circle on the screen, follow the flash, and keep the frequency flickering after release; Press the K1 key for more than 3 seconds, the LED flickers at 5Hz frequency, draw a red circle on the screen, follow the flash, and keep the frequency flickering after release; Press the K2 key, the LED goes out; Press the K2 key, the LED always shines.)
