| Abstract |
In this paper, a novel PWM control scheme for three-phase current source converter is proposed.
In this method, pulse widths composing input currents are decided so as to be proportional to the
source voltage. By overlapping the control signals to devices, it can be avoided the occurrence of
open circuit operations and PWM signal patterns can be simplified effectively. It is proper for the
digital control system. In this paper, this PWM control pattern is introduced. Furthermore, it is
clarified by several experiments that the theoretical discussions are appropriate. |
