Abstract: This paper focuses on developing an interchangeable electromagnetic contactor that essentially features with high power efficiency, low electromagnetic noise, and high power resource usage. The magnetic coils of this new IC-controlled method can be excited by AC or DC voltage and the range of the operating voltage is shown to be much larger than the conventional contactor. A wide range of applications for the new contactor is obtained. According to the electric performance requirement, the proposed controlling method, the pulse width modulation (PWM), provides a suitable energy for the exciting coils under the different operating condition. This is resulted in a stable operation between closing or opening process of the contactor greatly leads to the reduction of noise and energy loss for the exciting coils. Thus, the using life of the contactor can be greatly extended. In order to prove the validity of the proposed controlling method in this paper, several experi!
ments had been performed and the results are shown the feasibility and reliability of the new design.
Keywords: Electromagnetic contactor, Electromagnetic noise, IC-controlled, Pulse Width Modulation, Energy, Using life.
