Tw o k inds of control princip le, con trol characteristic and response speed are introduced in detai.l Principles andmethods of mi proving response speed are studied. A hybrid triggering method of h igh voltage selfexcitation and low volt age externalexcitation is proposed to reduce the response tmi e of MCR. It is show n by computer smi ulation resu lts that the response tmi e can be shortened to 30 m s by using th is method.
