Answer to Question #146469 in Electrical Engineering for ng wei yeh

Question

Many electronic appliances and equipment such as computers, televisions and advertising boards requires dc voltages to operate the electronic components and parts in them. Starting with an ac voltage supplied to the homes or offices, a steady dc voltage can be easily obtained by rectifying the ac voltage, filtering to a dc level and regulating the dc output to obtain a desired fixed dc voltage to power these appliances or equipment. Nowadays, integrated circuits have been widely used to obtain regulation. As an electronic engineer, you have been asked to design a regulated dc power supply employing IC voltage regulators based on the engineering principles you have acquired. Your design must provide an adjustable dc voltage output.
