基于CPLD+单片机的高频电刀设计

Design of High Frequency Electrotome Based on CPLD+Singlechip

通过在复杂可编程逻辑器件(CPLD)上,使用VHDL语言实现直接数字频率合成(DDS)技术,单片机通过输出端口对CPLD进行控制,产生控制功率模块的波形信号,通过高压隔离系统控制功率模块,来驱动输出变压器,产生高频电刀的高频高压输出,从而实现电切和电凝的功能。

This paper recur to direct digitaI frequency synthesis（DDS） technoIogy reaIized on CPLD with VHDL.SingIechip controIs CPLD by the output port through the procedure so as to produce the signaI for power moduIe.Then the high pressure shieIding system controIs the power moduIe so as to drive the output transformer for the high-frequency and high-pres-sure output of high frequency eIectricity knife.Thereby reaIize the function of eIectric-cut and eIectric-conguIation.
