Calculations reveal the value of efficiency
A few back-of-the-envelope estimates show why it pays to maximize power supply efficiency. Chris Harman • Puls l.p. Engineers are becoming more sensitive to efficiency when selecting a power supply. Energy flows through the supply, and something less than 100% of that energy can be used because of inefficiencies of power supply components. The difference […]
