Careers in Semiconductor Industry & Apprenticeship M.Eng. Programs

2008-02-21T02:09:00.000-08:00

The semiconductor industry is one of the most dynamic industries worldwide, which is estimated to be at $276.9 billion in 2008 (by SIA). In Malaysia, this industry is dominant in terms of employment creation by producing over 40% of estimated 397,553 electronics industry job opportunities in 2006. To be very successful in this industry, it is no longer sufficient for young graduates to merely be excellent academically, but need to have competitive advantage such as skills and higher education level due to highly skilled nature of the work involved. ICmic-UniKL Academy will present a career talk about the semiconductor industry and opportunities. The talk will cover the job market, industry requirements and employers expectations. There are important steps needed to best prepare for the career in this industry especially the right program for competency development in IC Design. To learn more about this industry and to have your enquiries

Conversion concept:

2008-01-02T20:49:00.000-08:00

Supply from TNB: 50Hz, 240V RMS (340V peak). Customer need DC voltage for welding purpose, say.

TNB sine-wave supply gives zero DC component!

We can use simple half-wave rectifier. A fixed DC voltage is now obtained. This is a simple PE system.

The function of the power converter stage is to perform the actual power conversion and processing of the energy from the input to the output by incorporating a matrix of power switching devices.

Power conversion refers to the power electronic circuit that changes one of the following:

voltage form (ac or dc),
voltage level (magnitude),
voltage frequency (line or otherwise),
voltage wave shape (sinusoidal or non sinusoidal, such as square, triangle, or saw tooth),
voltage phase (single- or three phase).

Power Electronics Systems

2008-01-02T20:16:00.000-08:00

Most power electronic systems consist of 2 major modules: Power Processor & Controller.

Power Processor : handles power transfer from input to output

Controller : feedback circuit; controls the amount power transferred to output or in order words, it tells the power processor of what to do by taking the measurement that happens at output and compared to input

Example: We have ac power input, but need dc input for charging the laptop, thus, we need something to convert that input

Goal of Electronic Power Conversion Systems

2008-01-02T20:13:00.000-08:00

To Convert electrical energy from one form to another, from source to load with highest efficiency, high availability, and high reliability, with the lowest cost, smallest size and weight.

However, of course there will be some compromise, but for a designer, these condition must be priory aimed.

Overview to Power Electronics

To date, there is no widely accepted definition that clearly and specifically delimits the field of power electronics.

In fact many experts feel that the name does not do justice to the field itself, which is applications oriented and multidisciplinary in nature, encompasses several electrical courses such as:

Digital and analog electronics,
signal processing,
magnetism,
electrical machines and power.,
control and
Computer, simulation and software
Solid-state physics and devices

The function of Power Electronics Circuits?
convert electrical power from one form to another using electronic device.

How?
Power electronics circuits function by using semiconductor devices as switches, thereby controlling or modifying a voltage or current.
