Design and implementation of an electric actuated valve for precise fluid control
(Gazi Universitesi, 2019) Kivanc,O.C.; Ustun,O.; Tosun,G.; Oguz,E.; Mutlu,Y.
Fluid control is one of the essential automation application area in industry. In order to fluid control effectively and precisely, valves which are crucial components, need a controlled rotating motion which leads to implement electric motors, electronic controller and gear systems altogether. In this study, an electric motor actuated valve system is designed and prototyped. The design phases are including switch mode power supply (SMPS) design, motor controller circuit design, mechanical implementation and controller design. The designed valve system is manufactured and tested using multi-disciplinary fashion. The application problems are solved by using the proper control techniques and strategies. The precise position control of butterfly disc is also achieved. According to the related industrial standard and application requirements, the experimental results show the effectiveness of the design approach. © 2019, Gazi University Eti Mahallesi.

Design of a position controlled electric actuator used in fluid control valves
(Institute of Electrical and Electronics Engineers Inc., 2016) Tosun,G.; Kivanc,O.C.; Oguz,E.; Mutlu,Y.; Ustun,O.
Valves are the main elements for controlling fluids in industry and other application areas. To control flow precisely, valves need a controlled action which leads to implement actuators, gear systems and electronic controllers. Increasing dominance of electrical actuators due to the advantages of easy control and intervention and space-efficient designs brings seldom implementation of hydraulic and pneumatic actuation. In fluid control applications, the main target is to obtain the right position, i.e. angle for rotary actuators, for adjusting flow rate. In this study, the design and implementation of a position controlled electrically actuated valve used for fluid control are presented. The design phases of system universal power supply and electronic control system are given and the experimental results of position control which are representing the validation the design study is also discussed. Also a special current control scheme is used to overcome transient disruptions. © 2016 IEEE.

Development of high efficiency multi-output flyback converter for industrial applications
(Institute of Electrical and Electronics Engineers Inc., 2016) Tosun,G.; Kivanc,O.C.; Oguz,E.; Ustun,O.; Tuncay,R.N.
This study presents the development processes of a high-efficiency two-output flyback-converter. The detailed design phases are presented together with encountered design obstacles, limitations and the methods to overcome them. Despite their widely use in industry, studies on high-efficient flyback converter design still remains a need. Most of the flyback converters are designed with multi outputs for their various input voltages. This study firstly describes the preliminary design stages, modeling studies and definition of magnetic and electronic components and PCB design processes followed by a prototype manufacturing. Modelling study is conducted in MATLAB/Simulink environment, and PCB design is realized in Altium Designer Software. Prototype is tested and its performance parameters are recorded. It is seen that the performance values are good agreement with those of design objectives. © 2015 Chamber of Electrical Engineers of Turkey.
