高壓高電流放電電路系統之設計

The Design of High Voltage and High Current Discharge Circuit System

指導教授 : 蔡正倫 林康平

摘要


摘要 心臟疾病為近年來的十大死因之一,一旦心臟出現問題往往在短時間就會造成患者的死亡,因此自動體外除顫器成為近幾年來各國政府極力推廣之急救器材。而本論文為研究自動體外除顫器除顫時所需高能量之電路系統。 本研究中主要設計一個可以耐高壓及大電流之雙向放電系統,其主要分為兩大部分,第一部分為充電系統,此部分主要配合升壓電路及高壓電容兩大因素,透過升壓電路將能量儲存於高壓電容上,並透過偵測電路及微控制器之控制,將能量做一個可調式之控制,使用者可以依不同需求來調整最終釋放之能量。第二部分為放電系統,放電系統主要著重在於放電之波形及系統耐壓及耐流之程度,藉由微控制器控制設計出一放電波形為雙向波形,並針對放電電路設計及元件的選擇做一探討,使系統能承受高壓高電流而不會造成系統損壞。 本研究依據自動體外除顫器之原理,設計一高能量除顫雙向波形,並實際動物實驗驗證其充電及放電效能。

Abstract Heart diseases have become the leading cause of death in recent years. Heart problems can cause death of a patient in a short time. Therefore, governments around the world have been promoting automated external defibrillator as a first-aid equipment in public places. The aim of this thesis was the study of the high energy circuitry required for defibrillation of automated external defibrillators. In this study, the main design was a biphasic waveform system, which can withstand high voltage and high current discharge. It included two major parts: the first part was the charging system which was consisted of a main booster circuit and a high voltage capacitor. Energy was stored in a high-voltage capacitor through the boost circuit. Via the control of microcontroller and the detection circuit the discharging energy was adjustable by request. The second part was the discharging system, which was mainly focused on the waveform and the extent of the system withstanding voltage and current. A biphasic discharging waveform was designed through the micro-controller. Additionally, the design of discharging circuit and component selection that the system can withstand high voltage and high currents without being damaged was discussed in the study. This study based on the principle of automatic external defibrillator high-energy to design the defibrillation biphasic waveform. An animal experiment was performed to verify the charging and discharging performance.
