Abstract
This paper is designed, simulated and implemented DC-DC interleaved Flyback converter controlled by Arduino Uno which converts input voltage from battery 12 V to 180 V DC at 20 kHz for 120 W. Digital control design is done with the use of Arduino Uno microcontroller. Simulation carried out using MATLAB/Simulation. The objective of this paper is to design a DC converter that operates at low cost with high efficiency via improving Flyback converter topology. This occurs using interleaved Flyback converter. To obtain a regulated output voltage of the interleaved Flyback converter, closed-loop feedback with PI controller is employed (Proportional – Integral). The duty cycle is varied to control the output voltage and produced constant voltage under variation input voltage and load disturbance. The designed technique uses voltage mode control (VMC) to obtain a constant voltage under continuous conduction mode (CCM). To implement the interleaved Flyback converter with the PI controller, the microcontroller Arduino Uno is used. The Simulation and the practical results give a little output ripple voltage, current, and high efficiency 6% compared with conventional Flyback converter.
