Abstract

Current control multiple level converter

similar to the multi-level voltage source converter having the capacitive grading

also has inductive current sharing issue of sub module. As for this issue

in this paper

a kid of current sharing modulation strategy based on dynamic bias PD-PWM is proposed for the new type module current control bridge arm multi-level converter for the reactive compensation

energy charging and DC power transmission

which solves effectively the current sharing issue of inductance of each sub module. In this paper

the operating principle of the scheme is described and the current sharing result of the control strategy proposed is verified by the simulation verification.
