Voltage Tracking of a DC-DC Flyback Converter Using Neural Network Control

Abstract

This paper proposes a neural network control voltage tracking scheme of a DC-DC Flyback converter. In this technique, a back propagation learning algorithm is employed. The controller is designed to improve performance of the Flyback converter during transient and steady state operations. Furthermore, to investigate the effectiveness of the proposed controller, some operations such as starting-up and reference voltage variations are verified. The numerical simulation results show that the proposed controller has a better performance compare to the conventional PI-Controller method.

Voltage tracking of bridgeless PFC cuk converter using PI controller

“…However, for low power application, BPFC Cuk converter is the most reliable converter because it offers low THD of input current, good power factor, easy to implement in transformer isolation, and natural protection against inrush current from start-up or overload current [7][8][9][10][11]. This converter acts similar to the buck-boost converter since it able to step up and step-down the output voltage by controlling the duty cycle [11,12] Basically, the DC-DC converter used power semiconductor devices that operated as the electronic switches which are refer as switched mode power supply [SMPS] [13,14]. The operation of this switching devices may cause inherently nonlinear characteristic of the BPFC Cuk converter [15].…”

Experimental Study of the Boost Converter under Current Mode Control

“…To obtain a constant inductor current under circuits parameters variation, the solution is the design of circuit that automatically adjust the duty cycle as necessary to obtain the desired inductor current, they are some works interessed by the tension mode control of DC DC converters to track desired output voltage, the paper [5] used the NNC method to decreasing overshoot and reducing settling time in the DC-DC Flyback Converter, otherwise some works used a control methods of DC DC converters to find the MPPT of the PV supply [6].…”

Development of Predictive Current Controller for Multi-Port DC/DC Converter

“…These power converters employ different control techniques to achieve control objectives [1]. The control objective could be target current [2,3] or voltage [4], the limit on a ripple [5], faster or slower response [6] and quick recovery from a disturbance or a stability criterion [7]. Traditional control techniques in both analog and digital domain have been in use for an extended period.…”
