Washington‚ DC Trip – 2012 My experience this year in DC was more laid back than last year. I felt that I knew the basics of what we were going to do so I could enjoy it more.

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.
