4. Product Principle

The arc suppression coil with magnetic bias realizes continuously adjustable electrical inductance through adjusting AC equivalent magnetic permeability by changing magnetic flux size of DC optimized magnetism on magnetic circuit of magnetized section of iron core, which has been set within AC operating coil. Its DC exciting winding is cascaded reversely so that the inductive power frequency voltage on the whole winding can be mutually balanced out. Exciting current of arc suppression coil can be controlled by closed-loop regulation to the output current of three-phase full-control rectifying circuit. Dynamic correction can be carried out to the modest non-linearity inherent in volt-ampere characteristics of this sort of arc suppression coil with adoption of data processing capacity of microcomputers.
