推箱子 源代码 大家可以参考学习一下……我爱vc(Sokoban everyone can refer to the source code to learn about ... ... I love vc)

说明：  经典的LLC论文，通过学习该文档，加深对LLC电路的理解。(Classic LLC thesis, through learning this document, deepen the understanding of LLC circuit.)

说明：  本模型为单项你变模型，将直流电逆变成方波，分别采用四个脉冲发生器控制四个igbt管，经滤波后得到输出结果。(This model is a single variable model. The direct current is inversely transformed into square wave. Four pulse generators are used to control four IGBT tubes, and the output results are obtained after filtering.)

PIC18系列单片机写的电压表，用1602显示(PIC18 family of microcontrollers written voltmeter, with the 1602 show)

解压后为多媒体电子琴源代码,希望大家喜欢！-unpacked for multimedia flower source code, hope you like them!

说明：  matlab雷达目标回波仿真，模拟整个发射和接收过程，对雷达信号进行目标回波信号的仿真。(Matlab radar echo simulation, simulation of the whole process of transmitting and receiving, simulation of radar signal echo signal.)
