Designing and Implementation of High Voltage Generator For Surgical Applications

A high voltage power supply is a very useful source which can be effectively used in many medical applications like medical imaging devices, blood analyzers, DNA equipment, robotic surgical devices and Electrocautery. In this study designing of High voltage circuit (2000 V) is proposed which can be used for medical applications. Generating high voltage low current can be achieved by use of Fly back converter for the optimum method which can improve the design of the circuit to decrease the size, simple and of low cost. The Fly back converter principle is analyzed to find the suitable design of the device in this study. An advanced Electrocautery high voltage circuit is designed and implemented in this paper consisting of four stages, Step-down Transformer 12 V Output, AC -DC converter, flyback transformer driver circuit (oscillation circuit) and flyback transformer high voltage output.
