One of the unique features of ASDEX Upgrade is the heating power with respect to the size of the plasma. The power at the separatrix divided by the major plasma radius P_sep/R representing the normalized heat flux at the divertor is 10 MW/m for 3 s. This is 2/3 of the power expected for a fusion power plant. In order to achieve this goal, the additional heating systems have been strengthened by four new ECRH gyrotrons. For power supply two 30 years old 70 kV / 2.5 MW high voltage AC power controllers have been rebuilt, equipped with a modern digital control system, integrated into the ASDEX Upgrade HV power supply system and optimized for the new task. The paper describes the reconstruction and installation of the power circuits and control system, commissioning, system optimization, operational experiences, present state and findings.

ASDEX升级的独特功能之一是相对于等离子尺寸的加热功率。分离线的功率除以主要血浆半径P _sep代表偏滤器处归一化热通量的/ R为10 MW / m，持续3 s。这是聚变电站预期功率的2/3。为了实现这一目标，通过四个新的ECRH旋流器加强了额外的加热系统。对于电源，已经重建了两个已有30年历史的70 kV / 2.5 MW高压AC电源控制器，配备了现代化的数字控制系统，已集成到ASDEX升级HV电源系统中，并针对新任务进行了优化。本文介绍了电源电路和控制系统的重建和安装，调试，系统优化，操作经验，现状和发现。
