effect of solar array capacitance on the performance of Switching shunt voltage Regulator
IEEE Transactions on Power Electronics, 2006Co-Authors: R A Kumar, M S Suresh, J NagarajuAbstract:Due to high power demand photovoltaic Regulators are being switched at high frequency. The solar cell capacitance increases the ripple voltage of the Switching Regulators at higher Switching frequencies. Increased ripple due to array capacitance is calculated and its effect in limiting the maximum design Switching frequency is studied. An experimental Switching Regulator is designed and used to confirm the theoretical considerations. This study has identified a method of solar cell capacitance measurement that is relevant to the design of a Switching voltage Regulator.

Varactor-Based Passive Ripple Filter With Automatic Tuning for Low-Noise Power-Supply Systems
IEEE Transactions on Power Electronics, 2017Co-Authors: Patrick J. Meehan, Donal G. O'sullivan, Aldrick S. Limjoco, Pat Mcguinness, James Jasper Macasaet, Jefferson Albo Eco, Thomas ConwayAbstract:Use of parallel resonance to notch filter the fundamental ripple frequency on a Switching Regulator output offers advantages in the combined metric of size and power compared to traditional low-pass solutions. Availability of barium strontium titanate varactors with capacitance of several nanofarads now makes automatic tuning of parallel resonance alignment with the ripple fundamental a feasible alternative. A phase-lock automatic-tuning circuit is demonstrated. The effective use of this technique as the power-supply filter used to power a 16 bit ADC is shown. The suitability of the resulting filter and Regulator to full surface mount encapsulation is demonstrated.

ISCAS (3) - Fuzzy logic controlled monolithic Switching Regulator in BCD technology
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 1Co-Authors: M. Criscione, L. Fortuna, A. Imbruglia, G. ScaliaAbstract:A monolithic architecture to realize a high-performance Switching Regulator with nonlinear fuzzy logic control is introduced. An overview of the main issues related to PWM DC/DC 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 main results obtained.
