This paper presents the analysis of a closed loop DC-DC boost converter for renewable energy applications such as PV. Most of renewable energy resources produce DC voltage that implied with DC-DC converters to convert their input voltage into a higher or lower voltage level accordingly to their application. However, there are numerous types of devices or applications that used renewable energy. Thus, it means the evolution of using a closed loop boost converter system must occur. The closed-loop system DC-DC boost converter is used to step up the low-level DC voltage to a high level of DC voltage. By varying the input voltage, the performance of boost converter in terms of its output voltage can be obtained and analysed. Several studies were conducted and validated with hardware implementation. All the results are recorded and show that various levels of input voltage can be converted into a fixed value of output voltage by using this converter. To emphasise, the boost converter generated 73.33 V output when an input voltage of 12 V. Whereas this experiment is conducted to analyse the boost converter performance so that can consider if this converter is compatible with the IR dryer system.

Black box modelling of infrared drying system for herbs dehydration

This study focused on development of infrared dryer system for Orthosiphon Stamineus leaves drying application. In any food technology, the dryer is the key component for quality drying food and herbs etc. An oven is modified to produce high technology drying system. A mathematical model is developed based on time response characteristics of the system. A second order model is found to adequately represent the system as it gives best fit with better properties than the first order model with error between measured data and simulation data is 0.44. Validation procedures show that the derived model is indeed a good enough representation of drying system. The infrared dryer system is highly non-linear and exhibits varying model parameters. An identification system is introduced to estimate the parameters and determine mathematical model of the system. ARMAX of na = 2, nb = 1 and nc = 1 polynomial model show best fit to experimental response of PRBS input.

Harmonic elimination simulation of seven level Cascaded H-Bridge Inverter Based on Newton Raphson method

2022-01-01 , Mohd Muqri Syahmi Sulong , Mohd Saifizi Saidon , Wan Azani Wan Mustafa , Muhammad Zaid Aihsan

Multilevel inverters for high-power applications are arising as the new breed of power converter options. Usually, they combine the waveform of the staircase voltage (from many dc sources) that has reduced the harmonic content. The selective harmonic elimination (SHE) by using Newton-Raphson method is proposed to apply for 350 W infrared dyer system. The analysis covers the scope for multilevel inverter single-phase cascaded H-bridge (CHB). The proposed SHE scheme is run using MATLAB/Simulink simulation. The results of these simulation is then compared to a 36 V output inverter hardware. The proposed SHE effectively removes the lowest-order harmonics and delivers a higher quality output waveform with a better harmonic profile.

Design and Simulation of High Gain DC-DC Boost Converter System for PV Application

Solar power plays a vital role in renewable energy systems as it is clean, sustainable, pollution-free energy, as well as increasing electricity costs which lead to high demands among customers. The main purpose of this paper is to develop an approach to designing a DC-DC boost converter for a standalone connected photovoltaic system with constant output voltage. A controller system DC-DC boost converter is designed to minimise losses and maintain at a particular value. The converter can increase a fluctuating voltage of the solar panel to an increased constant DC voltage. It uses voltage feedback to maintain constant output voltage. The controller is therefore designed as the heart of the closed loop system and offers pulse-width-modulation signal for control of the power electronic device in a boost converter. The boost converter can direct connection to the photovoltaic system grid-connected inverter. Simulations to describe the design proposed have been performed. Simulation work with the designed 75V output voltage boost converter in continuous driving mode was carried out. The test results show that the design proposed is successful.
