The ISKRA-5 pulse laser device is assigned for research in nuclear fusion.It has 12 channels working synchronously against common load to provide different experiments on thermonuclear targets heating. As the main power supply it uses the stored capacitor energy. The power used (67 MJ) is sufficient to cause fatal damage. Thus, safety must be guaranteed. Therefore ensuring of power supply reliability is one of main functions of control system. This requirement can be satisfied by improving power supply viabilty, the stability increase using optimal mode of the capacitor battery charge and by emergency energy discharge when one of the capacitor sections fails.
