The analysis of main reasons of biologically active dose growth during medical X-ray diagnostics was made. The methods of dose reduction to the patient by guaranteed X-ray emitter power providing and supplying voltage form improving were considered. Comparative technical characteristics of power source which implements the new principles of voltage control was given. The results of developed X-ray power source introduction to industrial X-ray equipment was described.
