Wearable devices require power management systems to achieve high conversion efficiency over a wide range of load currents. Multi-mode mixed modulation can be used in DCDC converters current range. The boost converter proposed this paper uses hybrid DGM (Deep Green Control Mode), PCMC (Peak mode control)-PFM (Pulse Frequency Modulation) and PCMC-PWM Width Modulation). switches smoothly from PCM...

In this work a monolithic architecture to realize a highperformance switching regulator with non-linear fuzzy logic control is introduced. An overview of the main issues related to PWh4 DCDC conversion in continuous mode is reported and an introduction to nonlinear fuzzy logic control is given. The main analog Fuzzy Logic blocks are illustrated and the overall architecture presented with the ma...

With the rising integration levels used to increase digital processing performance, there is a clear need for multiple independent on-chip supplies in order to support per-IP or block power management. Simply adding multiple off-chip DCDC converters is not only difficult due to supply impedance concerns, but also adds cost to the platform by increasing motherboard size and package complexity. T...

This research article addresses the evaluation of power conversion on heavy payload tethered hexarotors where the payloads are high and hovering times are long. Modifications were added to the power conversion unit based on operation reliability perspective. Since the objective power conversion is large comparing to existing tethered UAVs today, a strategic engineering approach was proposed and...
