It combines t he mer- its of t he Smart Power IC and digital trigger, and produces trigger pulses w it h perf ect performance and high sy mmet ry. M aking full use of t he resources of sing le 2 chip computer, it realizes phase self adapt ive, protect ion and parameter adju stment on line. It can be used in cont rolling st eady volt age and steady current of load.
