I’ve heard that setup for RF superimposed DC is complicated. What are the main pitfalls to avoid?
Proper arc handling setup is key to success with RF/DC because two different types of power are working simultaneously. The DC or pulsed-DC power supply can more accurately identify and respond to arcs than the RF power supply. Therefore, your DC power supply must be able to control your RF unit to shut off both DC and RF power when an arc occurs. It must also be able to quickly return power once the arc is extinguished. DC power supplies on the market today vary in this regard. While some offer no built-in DC/RF control method whatsoever, others offer powerful control. For example, Arc-Sync™ technology enables Pinnacle® Plus+ DC power supplies to easily and effectively control a connected Cesar® RF unit in order to handle arcs. There are additional issues to keep in mind when setting up RF/DC, such as cabling and the use of a filter/combiner. For more information, please see our Arc Handling in RF-Superimposed DC Processes application note.
