Realization of one chip for opto-couplers in driving circuit of electric valve

전동밸브의 구동회로에서 Opto-Coupler들의 one chip화 구현

This paper has been studied driving circuits in electrical valves. Also in this paper, opto-couplers of driving circuit are replaced with digital one chip of Altera company. Designs in order to realization of one chip are carried out with Altera Max Plus II. For compact size and light weight, the realization with one chip is necessary in the electrical valves. This paper has designed and presented the digital schemetic circuits, finally the driving circuits are sucessfully operated with the designed chip and showed the saving of area in the driving circuits of electric valves.
