DC-DC converters are widely used as reliable power source for many industrial and military applications, computers and electronic devices. Several control methods were developed for DCDC converters control mostly with asymptotic convergence. Synergetic control (SC) is a proven robust control approach and will be used here in a so called terminal scheme to achieve finite time convergence. Lyapou...

This application note describes the use of a Fairchild QFET (FQP60N03L ) in the power supply (DC-DC converter) of computer microprocessors. Chapter 2 describes QFET’s organizational features and the improvements in its electrical characteristics based on these features. Chapter 3 outlines the required input voltage and current based on the latest trends in microprocessors, and describes the opt...

This paper presents the design of simple but powerful soft switching scheme for a DCDC Boost Converter with a closed loop control. A new novel soft switching scheme is proposed with a single switch and minimum components which offers load independent operations. The only switch used in this converter is switched ON at zero current and switched OFF at zero voltage .The proposed Controller is use...

In this work, we analyze the impact of output filter design techniques aimed to reduce conducted emissions at a DCDC power converter. A thorough analysis, based on high-frequency circuit models converter, is performed assess expected improvements offered by different strategies. This analysis then confronted with measurements 300 W 48 V 12 Phase Shift Full Bridge (PSFB) prototype. Those experim...

A self-powered autonomous RFID device with sensing and computing capabilities is presented in this paper. Powered by an RF energy-harvesting circuit enhanced by a DCDC voltage booster in silicon-on-insulator (SOI) technology, the device relies on a microcontroller and a new generation ICRFID chip to wirelessly deliver sensor data to standard RFID EPC Class-1 Generation-2 (Gen2) readers. When th...
