MINISTRY OF SCIENCE AND TECHNOLOGY DEPARTMENT OF TECHNOLOGY AND VOCATIONAL EDUCATION TECHNOLOGICAL UNIVERSITY‚ MAWLAMYINE DEPARTMENT OF ELECTRONIC ENGINEERING PROJECT REPORT ON REGULATED DUAL 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

(buck) switching converters are integral to modern electronics. They can convert a voltage source (typically 8 V to 25 V) into a lower regulated voltage (typically 0.5 V to 5 V). Stepdown converters transfer small packets of energy using a switch‚ a diode‚ an inductor and several capacitors. Though substantially larger and noisier than their linear-regulator counterparts‚ buck converters offer higher efficiency in most cases. Despite their widespread use‚ buck-converter designs can pose challenges to

light waves in a laserbeam are aligned with each other‚ while the light waves from a flashlight are arranged randomly. The significance of this difference will become apparent as you read about the nature of light. Lasers come in all sizes—from tiny diode lasers small enough to fit in the eye of a needle to huge military and research lasers that fill a three-story building.And different lasers can produce many different colors of light. The "light" produced by carbon dioxide lasers and neodymium lasers

resonant snubber is presented in this paper. The passive snubber circuit‚ which is composed of two diodes‚ two capacitors‚ and one coupled inductor‚ ensures a zero current turn-on and zero voltage turn-off conditions for the power switch‚ and alleviates the reverse-recovery problem for the output diode. Moreover‚ with the proper design of the snubber circuit‚ the power switch and output diode can be softly switched in a wide load range. The operating principle and performance analysis of the

shore‚ he sees a shadow of a man. The man‚ whose name is Ben Gunn‚ tells Jim that Captain Flint marooned him on the island three years ago. A substantial amount of men were dead‚ so Silver decides to ask for a truce. Jim and Silver intentionally tell the pirates where the treasure is‚ and when they get there they are shocked to find that it is not there. Captain Silver then leaves the pirates on another island with supplies. Ben Gunn reveals that he dug out the treasure secretly and gives it to

Leigh‚ feeling that he lacked the international expertise to answer all the questions Rothschild might raise‚ had suggested that John Gunn of the bank’s International Division be included. The meeting had focused on the exchange risk related to the new sales contract. Dozier’s bid of (British pounds) GBP1.175 million to install an internal security system for a large manufacturing

1. Introduction Blu-ray is a new optical disc standard based on the use of a blue laser rather than the red laser of today’s DVD players. The standard‚ developed collaboratively by Hitachi‚ LG‚ Matsushita (Panasonic)‚ Pioneer‚ Philips‚ Samsung‚ Sharp‚ Sony‚ and Thomson‚ threatens to make current DVD players obsolete. It is not clear whether new Blu-ray players might include both kinds of lasers in order to be able to read current CD and DVD formats. The new standard‚ developed jointly
