SYSTEMS AND METHODS FOR REDUCING ARCING IN VACUUM OR PARTIAL VACUUM FURNACE USING DC POWER

Abstract:

A sintering furnace may include a furnace chamber and a retort located within the furnace chamber that receives a part to be heated. The furnace may also include one or more heating elements positioned around the retort and a power controller including power modules connected in series. The power modules may be operably connected to the one or more heating elements and may provide a direct current (DC) power output. A controller may selectively control the power modules to supply power to the one or more heating elements.
