Abstract
To reduce the impact of the high current on the power grid from the start process of the large induction motor and eliminate the negative influences of traditional reduced voltage start on the electronic and mechanical equipments and enhance the ability of the energy saving of the system. We studied and improved the intelligent soft start of such motors, this paper presents the design of intelligent soft starting controller in viewpoint of energy saving for power electronic systems. The proposed controller was compared through experimental studies under identical conditions with the thyristor soft starting controller (conventional controller). The performance comparison is made on the aspects of power quality and energy saving advantages. It is found that
the proposed controller has superior operating and performance characteristics as compared to the conventional one.
