Hybrid Modulated DCDC Boost Converter for Wearable Devices

A Buck-Boost Hybrid DC-DC Converter for Wearable Health Monitoring Devices

A hybrid approach of the DC-DC conversion is presented for battery-operated portable electronics systems such as wearable health monitoring devices. A switched-capacitor (SC) DC-DC converter is steered by hysteretic control to provide buck-boost conversion with a flexible conversion ratio, and its output is regulated by a low-drop-out (LDO) regulator delivering a low-ripple DC output. The SC DC...

Conducted EMI of Switching Frequency Modulated Boost Converter

In this paper conducted electromagnetic interference (EMI) of boost converter with switching frequency modulation (SFM) is theoretically analyzed in details. In the analysis line impedance stabilization network parameters, power inductor and input filtering capacitor parameters are taken into account. The analysis shows that the conducted EMI attenuation due to the use of SFM depends not only o...

Hybrid Fuzzy-pid Controller in Buck-boost Converter

Different types of controlling methods are used in switched mode dc-dc converters and the controller which is simple and of low cost is always in demand. The different controllers used are PI controller, PID controller and Fuzzy logic controller. PI and PID controllers do not give good performance in non linear conditions. Fuzzy logic controller is a non linear controller which do not need exac...
