Objective： Through getting acknowledge of the High-voltage of medical linear accelerator, it makes it possible for the relative medical workers to do a quick reaction to the repairmen and maintenance to the accelerator, and to maintain the machine to a good performance efficiently. While through understanding the application situation and development of accelerator, we could do a better choice at the terms of choosing an accelerator for hospital which meet the basic requirements and accuracy. Methods： Using the block diagram to introduce the main part of High-voltage of medical linear accelerator, and especially introduce the charging pinciple of charging transformer and the charge and discharge of PFN. The accelerator plays a vitalfuction at radiation therapy, and we introduce the accelerator application in various fields and the development situation of technology application. Results： It＇s significant to know the working principle of High- voltage as it＇s helpful to ensure whether the machine works normal or not and to diagnose faults in it. Conclusion： In addition, through understanding the application situation and the development of accelerator, we could choose an appropriate accelerator for our hospital.
