The Given

<p>This proposal proposes a DC/DC Buck Boost converter which has been used as a smooth starter for a DC Permanent Magnet Motor. In the existing system the DC/DC Buck Converter is used which provide the output less than the input Signal. Using buck converter it is difficult to increase the value of the input signal. Hence DC/DC Buck- Boost Converter used from which it is possible to get both the increased and decreased output from the given input. Previously pulse width modulation signals with respective to motor voltage is used. However they produce variations in the voltage and current of the motor. The above problem is overcome by using DC/DC Power converter. The proposed system with reduction in size, reduced ripples and increase in speed makes the system to operate at both low and high power applications. The proposed system results in higher efficiency, reduces the ripple content and the stress. The results are validated through MATLAB/Simulink and real time implementation.</p>

This paper describes a modularized smart system architecture which is integrated with Internet of Thing (IoT) into the DC-DC converters to build a programmable technique to leverage machine learning algorithms to predict possible future faults to the system. In addition, it facilitates the performance optimization of the boost converter. This system can be established with low computing hardware to simulates the control behavior and data-driven method of IoT-based, due to the unreliability initiated from the integration of IoT technology and power electronic converters. In response to these challenges, the current paper addresses a scientific approach using small signal analysis of dc-dc boost converter (non-Ideal) with closed loop control to analyze the small deviations or abnormalities in transient region and the steady-state operating point. Complete state-space analysis is done to obtain output voltage using pulse width modulation techniques for boosting the voltage of the input voltage to a higher level by momentarily storing and release the energy in the conductor. The model of the converter is designed and simulated using voltage mode controlling method. Digital implementation based on Arduino platform was implemented to compensate perturbations of sudden load variation either on voltage or current loads. A Simulation study is conducted to validate the result of the step-up dc-dc converter using MATLAB.

This paper presents the design of an Interleaved DC/DC Boost Converter for the implementation of an Electric Scooter. The output of the power converter can be controlled using the Pulse Width Modulation (PWM) switching technique to boost 12V battery supply to power a 24V Brushed DC Motor with improved efficiency compared to conventional converters. The design of the power converter was calculated for different number of interleaving phases. The simulation is carried out using MATLAB/Simulink for 2, 3, 4, 6 and 8-phases interleaved converters to compare their performances. The 4-phase is selected due to its advantage and further implemented in the prototype. PWM output switching frequency is set to 25 kHz with 4 signals of 90° phase shift to each other. The testing on a complete prototype was carried out.

Oriented Approach

This paper is focusing on the stability analysis of the voltage mode control buck converter controlled by pulse-width modulation (PWM). Using two different approaches, the nonlinear phenomena are investigated in two terms, slow scale and fast scale bifurcation. A complete design-oriented approach for studying the stability of dc-dc power converters and its bifurcation has been introduced. The voltage waveforms and attractors obtained from the circuit simulation have been studied. With the onset of instability, the phenomenon of subharmonics oscillations, quasi-periodicity, bifurcations, and chaos have been observed
