介绍了一种基于DSP 的高频感应加热电源。现以MOSFET为开关器件，并通过逆变器并联扩容为60kW/300kHz。采用多重斩波技术，增大了斩波电路的容量，将基于DSP 的fuzzy-DPLL 复合数字锁相环技术应用在高频场合，使锁相有快速的动态性能和高精度的稳态性能，实现了对负载频率的可靠跟踪及对逆变状态的可靠控制，提高了逆变器 的工作效率和功率因数。(A high frequency induction heating power supply based on DSP. MOSFET is now used as a switch device, and the capacity of 60kW/300kHz is expanded in parallel through the inverter.Using multiple chopping technology, the capacity of chopper circuit is increased, and the fuzzy-DPLL composite digital phase locked loop technology based on DSP is applied to the high frequency situation, so that the lock is locked.It has fast dynamic performance and high precision steady state performance. It achieves reliable tracking of load frequency and reliable control of inverter state, and improves inverter.Working efficiency and power factor.)

开发环境c++ builder 6.0。主要功能是实现ie浏览器，可以在当前并且是同一窗口打开网页，一直都是全屏状态，没有关闭最小化和最大化按钮，并可以使浏览器没有滚动条。-Development environment c++ Builder 6.0. Main function is to achieve the ie browser, you can in the current window and open the same page, has been in full screen mode, there is no closure to minimize and maximize buttons, and allows browser does not have scroll bars.

说明：  使用STM32F407进行以太网通信,并涉及到数据链路层的工业以太网通信,使用LWIP协议栈(STM32F407 is used for Ethernet communication, which involves industrial Ethernet communication in data link layer, and LWIP protocol stack is used.)

Matlab文件，一种无桥buckPFC电路，具有高效率(Matlab a kind of bridgeless buck PFC converter)

C#在窗口的状态栏中添加一个带图标的文字标签，看上去更美观了，虽然简单，但以后再写一些程序的时候说不定能用上。

求两个序列的相关关系的fortan程序 -For the correlation between the two sequences of fortan procedures

利用vi编写的万年历，很实用，很简洁，易上手。(VI prepared by the calendar, it is practical, very simple, easy to use)

说明：  The JS special effect code is based on jQuery + CSS3 to realize the special effect of digital clock.

说明：  对微电网的经济性进行优化调度，有需要的 可以借鉴参考(It can be used for reference if necessary to optimize the economic dispatch of microgrid)
