Power Supply Regulation DC-DC voltage converters are often used to provide a regulated voltage supply from an unregulated voltage source. Unregulated voltage sources can be rectified line voltages that exhibit fluctuations due to changes in magnitude. Regulated voltage supplies provide an average DC output voltage at a desired level (3.3 V‚ 2.5 V‚ etc.)‚ despite fluctuating input voltage sources and variable output loads. Factors to consider when deciding on a regulated voltage supply solution include:

Case Study #1 - Sunspot‚ Inc 1. What are the most likely benefits of forming strategic supply alliances with Sunspot’s key suppliers? A strategic alliance between Sunspot and its key suppliers will result in a relationship based on trust. It’s key for both parties to develop and manage this “institutional” trust or the alliance will fail. Trust will facilitate communication which will lead to less errors and higher quality‚ faster development times‚ and lower costs. Synergies created by

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

scheme DC-DC converter. The converter is a phase-shifted full-bridge PWM converter that is designed to operate as a front stage of a power conversion system where the input is a variable low voltage high current source. The converter is designed to step-up the low voltage input to an acceptable level that can be inverted to a 120/240 VAC 60Hz voltage for residential power. A DSP based adaptive control model is developed‚ taking into account line variations introduced by the input source while providing

Case Study Finance 405 After receiving a telex from the Controller of the Irish plant‚ who is an integral employee at Universal Circuits‚ we had to make a tough decision regarding his request to hedge against the US dollar depreciating. If the US dollar depreciates‚ manufacturing would be shifted from his Irish plant to the US plants‚ which in turn would negatively affect his potential bonus. We acknowledge this risk

Unlimited Power Supply Before I came up wit the U.P.S. (Unlimited Power Supply)‚ I was struggling with an idea for this science fair. However I thought of a magnetic car. Then after school I heard my parents saying that our electricity bill was getting too high‚ so I tried to think of a solution. Then I read an article about how a Prius battery could power a house‚ and then I thought about how I could power a house using a rechargeable battery like is found in the Prius. Then I came across the Bedini
