Abstract : A DC power supply is very important in our day to day life. We use it to charge or operate our DC components like charger light‚ cell phone battery charger etc. It’s nothing but a AC to DC converter. Keywords: 5V DC power supply‚ rectifier‚ diode‚ filter‚ capacitor‚ zener diode‚ voltage regulator‚ signal‚ waveshape. 1. Introduction I’m designing a 5V DC power supply. Here I’m basically designing a AC to DC converter. To convert the AC to DC‚ I’m using components like full wave bridge

VOLTAGE DC POWER SUPPLY Supervisor: U Thein Min Wai ABSTRACT The regulated power supply converts the standard 220 volts‚ 50 or 60 Hz AC available at wall outlets into a constants DC voltage. It is one of the most common electronics circuits that we can find. The DC voltage produce by a power supply is used to power all the types of electronic circuits‚ such that television receiver‚ stereo system‚ CD players and laboratory equipment. The regulated dual voltage DC power

nature is. Out of all the possible literary works that have a theme about nature there’s three in particular that are going to be described in this essay. These three works are "A Description of New England‚" by John Smith‚ "Rip Van Winkle‚" by Washington Irving‚ and "Thanatopsis‚" by William Cullen Bryant. Each has a very good way of conveying nature and how stunning it is to them. In "A Description of New England‚" John Smith talks about how amazing the nature is in the new world. He did this
