Compensation of input impedance by digital control for high voltage convertor

Abstract

In this paper, there is presented the digital control of input impedance for high voltage converter. Paper include measurement and evaluation of input impedance performed on auxiliary converter to UIC code 550-2 OR 1st edition and UIC550-3 O, 1st edition standards. The proposed control scheme is created for maximization input impedance for every frequency of injected input voltage.
