DDPE 3103 INDUSTRIAL ELECTRONICS
Lecturer : AP Dr. Morina Binti Abdullah
En. Kamaruddin Tawi
Semester : 1 2016/17
This course covers topics on Electronics and Mechanical Switches and Relay and followed by the topic on DC Power Supplies. The course will also discuss on oscillator which include sinusoidal and square wave generated oscillators.For the power electronics devices the topic includes thyristors such as SCR, Triacs, Diacs and its application. Lastly the power control switching circuits such as Unijuntion transistor (UJT) and Programmble Unijunction transistor (PUT) will also be discussed.

- Topic 1
Topic 1TOPIC 1 : SWITCHING CIRCUITSTopic 1 is about switching circuits. This topics include the mechanical and solid state switching circuits. Mechanical switches is categories as permanent and momentary switches. For relay topics it include mechanical and solid state relay.
- Topic 2
Topic 2TOPIC 2 : DC POWER SUPPLYIn this topic students will be able to understand the circuits and components involve in designing a dc power supply. These circuits are rectifier, filter and regulator. For the rectifier circuit the full wave rectifier circuit will be discussed with its dc output calculation and the waveform of the circuit. Filter circuit consist of a capacitor and the calculation involve the dc and ripple voltage. Finally the regulator circuits are using transistor , op-amp and the IC regulator.
- Topic 3
Topic 3TOPIC 3 : OSCILLATORSinusoidal and square wave generated oscillator are discussed. The sinusoidal oscillator include the Phase shift, Wein bridge, Hartley and Colpitts oscillators. A brief discussion of the crystal oscillator is also discussed. For the multivibrator circuit the students will able to differentiate a astable, monostable and bistable oscillator circuits. Lastly the topic on circuit using comparator and Schmidt trigger on generating square wave will be discussed.
