Laboratory experiments in undergraduate, diploma and certificate courses are often used to assist and complement the classroom lectures. They are an important tool for improving students hands-on skills like measuring, corroborating practical results, comparing theory and practice, modeling, etc. But the complexity of the power electronics systems makes the laboratory experiments implementation not so simple. The Power Electronics field is very multidisciplinary. There are also class time restrictions in virtually all courses, and one of the lecturers challenges is to adjust the deepness and the broadness of the used approach. In this context, well planned teaching equipment can help a lot. It can save class time and spur students motivation.
In this teaching module, the two fundamental topologies of non-isolated dc-dc switching converters which are the buck and the boost converter are developed in one platform. This interactive 2-in-1 buck and boost converter teaching module is developed to demonstrate these two basic topologies in order to help the student understand and visualize the circuit elements clearly. With the concept of plug and play, student can play around with placement of energy storage elements and switching devices to construct either buck or boost converter. On the other hand, students can also varying the output voltage for both converters by adjusting the PWM duty cycle which is microcontroller based. The novelty of this invention is that the adopted concept in this teaching module is to divide the power electronics systems in three modules: the power converter module, which comprises the switching devices and the energy storage elements, the PWM controller module and finally the gate driver module. It was found that this arrangement provides a better understanding by the students and the utilization of the modules in a broader diversity of experiments compared to the available teaching module. In this module, the switching devices and the storage elements positions in the power converter module are allowed to change. Therefore, the same power module can be used to implement either buck and boost converter. Furthermore, the switching devices and the energy storage elements are placed in a visible enclosure in order to help the student visualize the circuit elements clearly. Another important feature is the Pulse Width Modulation (PWM) controller module in this teaching module is microcontroller based which is novel.

Light Sensitive Field Effect Transistor (LISFET)

This project present about development of MOSFET which operate with photoconductive cells application (LISFET). Most commercially available photoconductive cells are manufactured from cadmium sulfide (CdS), which is sensitive to light in the visible spectrum. CdS photoconductive cells (CdS cells) are often referred to as light dependant resistors (LDR). The fabrication of LISFET consists of two device fabrication processes namely the fabrication of a CMOS technology and the fabrication of photoconductive cells.

Low Cost Embedded Portable Herb Leaves Recognition System

Malaysia is an agriculture based country, which 70% of population depends on agriculture. There are need for ability to find and identify different kind of agriculture plants and herbs effectively for the purpose of finding and collecting. The identification of herbs plantation currently is ineffective and inefficient through manual process by trained human resources. This manual process of identifying useful herbs causes ineffective collecting and identifying of the natural resources. The manual approach involves expert human being based on leaves recognition. For huge area a researcher or expert required to cover a huge searching area which causes a lot of time and energy. The propose embedded system for identifying herbs through leaves recognition or what is called as A Low Cost Embedded System for Portable Herb Leaves Recognition System "" developed using concept of Image Processing Techniques and Neural Network Algorithms will ease the searching and identifying useful herb plants. This product describes techniques applied for hardware and software design of the devices. It involves edge detection, template matching and back propagation neural network to provide reasonable accuracy and speed.
This is the only product of this kind which implements image processing techniques and neural network algorithms using low cost embedded system design platform. This device enables leaves to be classified plants type. The plants type defined by it scientifically use for medical purposes. Biological data are obtained using Leaf Area Index (LAI) for the identification of the useful plant. The numbers of expertise in recognizing range of leaves are scarce. The needs of experts are required in order to find and identify leafs for collecting useful herbs for medical purposes. The numbers of herbs (which can be identifying by the unique pattern of leaves) are huge and it is impossible to provide enough people to perform the tasks. With the help of this device the finding and collecting herbs can be made more effectively and efficiently and also helps us to generate more expertise in recognizing range of herb leaves.

Mobile DC to AC Universal Power Supply / Charger

"i) As a mobile power supply / charger to notebook PC users that always travel by cars.
ii) As an AC power source to power-up selected household electrical appliances that
having power less than 120W directly from a car battery.
This product is an adapter that converts 12Vdc into 240Vac so that most common relatively small powered AC appliances to be used inside the car. The adapter is actually a 120W switching-mode power inverter (SMPI) that generally will power-up selected AC appliances. The SMPI uses the reversed technology of a typical switching-mode power supply (SMPS) and in-fact the step-up transformer used was taken from a similar rated designed power of an SMPS.
The 12Vdc supply is chopped through a MOSFET with a frequency of 25kHz to get a high frequency DC pulses that input into a high-frequency switching transformer which steps up to high voltage 240Vac with the frequency of 25kHz. Then, the voltage is rectified and filtered to a high-voltage smoothed DC and goes through an H-bridge inverter where the output produces 240Vac, 50Hz to a given AC load.
This invention uses a relatively small high frequency switching transformer which works on high frequency DC switching pulses of 25kHz, which is very much lighter, smaller and low-profile sizing compares to its conventional predecessors.
The product is highly potential to traveling businessmen and field worked personnel that always find necessary to have a portable source of AC supply that simply can be plugged into a car???s cigarette lighter supply, as to power-up their relevant appliances."
