Single-inductor multi-input multi-output (SI-MIMO) dc-dc converters are attractive in the engineering applications due to advantage of high power density and low cost. In order explore as many possible SI-MIMO topologies, this article proposes a simple effective topology derivation principle that only requires three steps. First, basic cells consisting single inductor multiple sets unidirection...

Abstract: Owing to the problems of DC side capacitor value choice in the application of Active Power Filter (APF), this article presents a technique based on the analysis of the ripple voltage in DC side by graining appropriately the undulation control rate within the range of settings and control DC voltage so that the voltage fluctuation rate can reach minimum value under the condition of spe...

Received Nov 21, 2017 Revised Jan 29, 2018 Accepted Feb 17, 2018 This paper presents a performance investigation of bldc motor employing KY converter. Conventional The landsman converter is used to minimize the ripples but the inverter produces high output power ripples, which in turn affect the output of the inverter in The proposed KY converter reduces ripples and smooth dc supply gives to th...

Abs t rac t -Piezoelectric transformers (PZT) can be used advantageously in high output voltage DC-DC converters . In such applications the output section includes a vol tage doubling rectification scheme to help increase the output voltage. This topology was modeled and analyzed by considering the expected voltage and current waveforms under the first harmonics approximation. The results were ...

This thesis presents the theory, design, layout and a proposal for measurement set up of a synchronous DC-DC buck converter. This converter will be used as the supply modulator of power amplifier of mobile phones. The design is done using 45nm CMOS technology. Pmos and nmos switches are synchronously turns on and off for DC voltage conversion. Second order LC type filter is used to filter out t...

In this chapter we treat difference propagation and input-output correlation in Boolean mappings and iterated Boolean transformations. Difference propagation is specifically exploited in differential cryptanalysis (DC), invented by Eli Biham and Adi Shamir [BiSh91]. Input-output correlation is exploited in linear cryptanalysis (LC), invented by Mitsuru Matsui [Ma93]. Both DC and LC were success...

A novel method of parallel switching power with different capacity in a controllable current sharing method is presented in this paper. It achieves proportional current sharing and stable output DC voltage by using controllable current sharing modes which output assignable feedback signals to the paralleling buck DC-DC converters. The validity and effectiveness are verified through comprehensiv...
