A new topology for non-isolated step-down dc-dc converters discards ferrite cores completely. The new Resonance Scaling Method results in use of 10nH resonant inductors even at 50kHz switching frequency and an effective factor of 1,000 times reduction of the magnetic size and weight of comparable buck converter at 50kHz.This opens a new power electronics era with the first true Power-Supply-on-a-Chip. </div> <div class="node-body article-body"><div></div>The groundbreaking PWM-Resonant Ćuk topology could revolutionize the design of non-isolated, step-down dc-dc converters.</div> <p><a href="http://powerelectronics.com/power-management/step-down-dc-dc-converter-eliminates-ferrite-cores-50khz-enabling-power-supply-chip" target="_blank">read more</a></p> http://powerelectronics.com/power-management/step-down-dc-dc-converter-eliminates-ferrite-cores-50khz-enabling-power-supply-chip#comments Power Management Mon, 10 Apr 2017 16:05:00 +0000 61471 at http://powerelectronics.com Semiconductors, Power Electronic Systems Roadmaps Point to the Future http://powerelectronics.com/power-management/semiconductors-power-electronic-systems-roadmaps-point-future <div class="field-deck"> Portrayed in roadmaps, future trends for power electronic systems will include semiconductors as well as other components and manufacturing impacts. </div> <div class="node-body article-body"><div></div>Portrayed in roadmaps, future trends for power electronic systems will include semiconductors as well as other components and manufacturing impacts.</div> <p><a href="http://powerelectronics.com/power-management/semiconductors-power-electronic-systems-roadmaps-point-future" target="_blank">read more</a></p> http://powerelectronics.com/power-management/semiconductors-power-electronic-systems-roadmaps-point-future#comments Power Management Wed, 05 Apr 2017 05:40:00 +0000 61461 at http://powerelectronics.com Understanding Test Challenges across the Power Semiconductor Life Cycle http://powerelectronics.com/power-management/understanding-test-challenges-across-power-semiconductor-life-cycle <div class="field-byline"> Wilson Lee, Senior Marketing Manager, Tektronix </div> <div class="field-deck"> The life cycle of a power semiconductor device involves a variety of test and characterization activities. </div> <div class="node-body article-body"><div></div>The life cycle of a power semiconductor device involves a variety of test and characterization activities.</div> <p><a href="http://powerelectronics.com/power-management/understanding-test-challenges-across-power-semiconductor-life-cycle" target="_blank">read more</a></p> http://powerelectronics.com/power-management/understanding-test-challenges-across-power-semiconductor-life-cycle#comments Power Management Sun, 02 Apr 2017 15:20:00 +0000 61451 at http://powerelectronics.com <p>1.
