6-41 Chopper Control and Monitoring System of HIMM

摘要

Chopper control and monitoring system plays an important role in HIMM (Heavy icon medical machine). It is used to control and monitor the outputs voltage of the pulse generator. The pulse generator outputs high voltage wave forms to 3 500 V on the basis of an input trigger, which requires +5 V 1 V into 50 Ω with a risetime of <20 ns togate. The Chopper control and monitoring system is designed and the structure of it is shown in Fig. 1.
