Öğe Design and implementation of switched reluctance motor driver for industrial controller(2013) Uysal, A.; Bayir, R.In this study, a driver design has been implemented for Switched Reluctance Motor (SRM). With this driver, Switched Reluctance Motors can easily be driven using industrial controllers. In addition, with some simple changes on driver, Switched Reluctance Motors with different phase numbers can also be driven. S7-1200 PLC (Programmable Logic Controller) was preferred for the test of the driver. PID (Proportional Integral Derivative) algorithm was used for speed control of the motor. PID parameters are automatically adjusted with PLC software. The performance of the driver was tested for different speed and load values using PID controller. © 2013 IEEE.Öğe Futuristic methods of electronics cooling(Elsevier, 2023) Uysal, A.; Keçebas, A.; Kayfeci, M.Power density for high-performance chips has recently increased due to advancements in semiconductors, other mini- and micro-scale electronic technologies, and continued miniaturization. Heat is generated when the current passes over a resistance, and internal losses are unavoidable. Electronic devices produce heat this way while working. This heat needs to be taken from electronic devices due to its effect on their performance. The fault ratio on electronic devices increases exponentially as the temperature increases. That is how high operation temperature occurs from heat production on electronic devices that are not controlled and designed to cause safety and performance decreases. This reality is to make it necessary for heat transfer, namely, developing cooling systems and new investigations, and to increase the importance of thermal control on the operation and design parameters of electronic devices day by day. In this chapter electronic device cooling methods are classified as advanced cooling technologies (active and passive cooling methods) with the goal of guiding future research while representing current application areas. © 2023 Elsevier Inc.

An inverter has been designed to drive the motor. The inverter circuit is controlled by fuzzy logic controller. The position of the rotor and the speed value is obtained from a magnetic sensor placed inside of the motor. According to the position of the rotor which phase of the motor is to be commutated is defined. The information of the error occurred in speed and the change in error is used as the input of the fuzzy logic controller. The speed of the motor can be adjusted to desired reference value by using implemented fuzzy logic controlled circuit. In the test setup prepared, the performances of PID (Proportional-Integral-Derivative) and fuzzy logic controllers has been compared by measuring the current, the voltage and the power of the motor. © 2013 IEEE.Öğe Fuzzy logic controlled brushless direct current motor drive design and application for regenerative braking(Institute of Electrical and Electronics Engineers Inc., 2017) Karabacak, Y.; Uysal, A.In this study, a driver design for the Brush Less Direct Current (BLDC) engine was made. With this driver, BLDC motors are provided to operate in both engine mode and regenerative braking mode. Fuzzy logic controller is used for motor speed control. The STM32F4 Discovery development card has been used to control your drive. Driver tests were conducted on an electric vehicle. Test data were obtained with the aid of a mini computer placed on the vehicle. In regenerative braking mode, the speed of the vehicle slowed down and the battery voltage was shown to be charged at the desired levels. The drive test data was obtained with the aid of an oscilloscope. © 2017 IEEE.
