摘要

电外科发生器(ESG)是目前临床手术中应用最广泛的外科技术。ESG的主要缺点是由于组织阻抗可变,其输出功率不规则。由产生的大量热能引起的散热会导致患者和外科医生的医疗并发症。在这项研究中,研究了各种逆变器拓扑结构和功率控制器,以指定确保最佳性能的最佳结构。所研究的逆变器拓扑类型为三电平和五电平,而所研究的PID结构为整数阶(IO-PID)和分数阶(FO-PID)。仿真结果表明,在最小散热率和输出电压和电流的THD方面,五电平逆变器的FO-PID优于三电平逆变器的IO-PID。

Comparative analysis of different inverters and controllers to investigate performance of electrosurgical generators under variable tissue impedance
Electrosurgical generators (ESGs) are currently the most widely used surgical technology for clinical operations. The main disadvantage of ESGs is their output power is irregular due to the variable tissue impedance. The heat dissipation caused by the high amount of thermal energy generated leads to medical complications for both patient and surgeon. In this research, various inverter topologies and power controllers are investigated to specify the best structure that ensures best performance. The type of inverter topologies investigated are three level and five level, while the PID structures investigated are integer order (IO-PID) and fractional order (FO-PID). The simulation results indicate that FO-PID with five level inverters is better than IO-PID with three level inverters in terms of minimum heat dissipation rate and THD of the output voltage and current.
