Description: 三菱梯形图转成51单片机HEX文件。
三菱软件写好梯形图，再运行转换软件，设定好51单片机的输入输出，
打开写好的梯形图，转换出的就是hex文件，烧录到51单片机，51单片机
就可以执行PLC的动作了。51单片机控制板价格便宜，可以代替简单场
合的PLC，控制成本降低。
1：把PWM转换后，在PWM文件下生成一个HEX文件。
2：生成的文件很大，51单片机要选用8K以上(AT89S52就是8K)储存量的。
3：把HEX文件下载到单片机就可以用了。
-Mitsubishi ladder into 51 single-chip HEX file. Mitsubishi software written ladder, and then run the conversion software, set 51 single-chip input and output, open ladder-written, conversion is a hex file, burn to 51 single-chip, 51 single-chip microcomputer can be implementation of the action of PLC. 51 Single-chip panel prices, can replace the simple occasions PLC, control and lower the cost. 1: after the PWM converter, PWM documents generated in a HEX file. 2: generate a lot of paper, 51 single-chip 8K to choose more than (AT89S52 is 8K) storage capacity. 3: The HEX file can be downloaded to a single-chip microcomputer used.

Description: 此开关稳压电源由AT89S52单片机作为控制核心。系统包括AD采样，PID控制，PWM输出，构成闭环系统。交流电源输入到整流模块，经整流滤波后输出平稳的直流电压。该直流电压直接输出至IGBT全桥变换器模块。高精度AD转换器将后端输出的电压电流信号由模拟信号量变为数字量供给单片机进行数字PlD运算，经过PID控制运算后，由控制模块输出PWM调制波形至IGBT栅极，构成一个闭环系统，控制电压稳定输出，从而实现开关稳压电源控制系统。此外，可由键盘输入欲得电压值，从LCD显示实际电压值，人机交互界面友好。-This switching power supply control by the core as a single-chip AT89S52. AD sampling system, PID control, PWM output, constitute a closed-loop system. AC power input to the rectifier module, after filtering by the rectifier output DC voltage stable. The output DC voltage directly to the IGBT full-bridge converter modules. Precision will be the back-end AD converter output voltage and current signals from the analog signal into a digital quantity to supply the number of single-chip computing PlD, after PID control algorithms, the control module from the output PWM waveform modulation IGBT gate to form a closed-loop system, the control voltage output, in order to achieve switching power supply control system. In addition, by欲得keyboard input voltage from the LCD displays the actual voltage value, user-friendly human-computer interaction.
