I. Introduction a. Back ground of the Study Triac The TRIAC is a three terminal semiconductor device for controlling current. It gains its name from the term TRIode for AlternatingCurrent. It is effectively a development of the SCR or thyristor‚ but unlike the thyristor which is only able to conduct in one direction‚ the TRIAC is a bidirectional device. TRIAC The TRIAC is an ideal device to use for AC switching applications because it can control the current flow over both halves of

controller in order to obtain the electromagnetic torque needed to reach the desired speed. Current controller controls the armature current by computing the appropriate thyristor firing angle or by using the firing gate angle. This generates the rectifier output voltage needed to obtain the desired armature current and thus the desired electromagnetic torque. This report also includes the work already completed and work planned for the next semester. Figure1: Proportional Integral control (PI)

DISTILLATION HISTORY • Distilling was used as early as 3500 BC in Mesopotamia where perfume makers had developed it as a technique for isolating the scented oils of flowers and plants‚ what we know as “attar”. • Around 1100 AD wine was first distilled to make spirit by Irish monks who travelled around Europe. • The results of distillation were considered to have magical powers and this led to alcohol being called “water of life” or “usige beatha” in Gaelic‚ “eau de vie” in French

single-switch chopper was discussed in Chapter 2‚ where it was shown that the average output voltage could be varied by periodically switching the battery voltage on and off for varying intervals. The principal difference between the thyristor-controlled rectifier and the chopper is that in the former the motor current always flows through the supply‚ whereas in the latter‚ the motor current only flows from the supply terminals for part of each cycle. A single-switch chopper using a transistor‚ MOSFET or

Waves Assignment Microwave Ovens Microwave ovens‚ or microwaves‚ are kitchen appliances which use microwave radiation to cook‚ heat or defrost food. Properties of a microwave: Microwaves are electromagnetic waves with wavelengths longer than those of Terahertz (THz) wavelengths‚ but relatively short for radio waves. Microwaves have wavelengths approximately in the range of 30 cm (frequency = 1 GHz) to 1 mm (300 GHz). The word microwave generally refers to "alternating current signals with
