Abstract

The development of electric-powered transportation has increased demand for electric vehicle chargers. Most chargers used are DC chargers since energy storage in electric vehicles relies on batteries. Therefore, a rectifier is required to convert AC power sources into DC. This study aims to develop a Vienna Rectifier for electric vehicle charging systems to achieve optimal power quality. The main focus is to enhance efficiency and power quality by implementing a PID control system to reduce Total Harmonic Distortion (THD) and improve the power factor. Simulations are conducted using MATLAB Simulink with the Clarke Transformation method to optimize voltage and current control. The simulation results show that the designed Vienna Rectifier achieves a THD value below 5%, in compliance with the IEEE-519 standard, with a power factor close to 1. This demonstrates that the application of PID control in the Vienna Rectifier can improve the efficiency of electric vehicle charging while reducing the negative impact of harmonics on the power grid.

Abstract

One of the steps in the tyre manufacturing process is the Tyre Building Machine. The tread is the last component to be fitted to the tyre carcass after all other components have been installed. When measuring the length of the pre-adjusted tread, errors or variations often occur in the measurements taken by the measuring device due to its lack of accuracy. This prevents operators from using the tyre tread and can result in a large amount of scrap and wasted time during the tyre manufacturing process. To overcome this problem, a redesigned tread length measurement system with a higher level of accuracy was created to minimise tread length fluctuations during tyre manufacturing. The results of the tread length measurement procedure using the ENC-1-1-24-N type rotary encoder can function according to the program created. This is validated by the tread length measurement data. The results of the HMI display design and the software created can operate according to the desired instructions. To change the tread length, the operator only needs to enter the number on the HMI panel.
