| Abstract: | On the basis of capacitor dropping voltage theory, a new control scheme of hybrid AC contactor based on the zener diode switching circuit was proposed. The circuit design and working principle were described, and the experimental verification was carried out. The results indicate thaL the new hybrid AC contactor can stably achieve the function of arcless closing and breaking. It can effectively enhance the working reliability and the service life of the contactor. The control scheme has the advantages of simple contral ,small size,low cost and universal property. |
