The Influence of the Number of Frequencies and the Frequency Repetitions Rates in Spread Spectrum Sigma-Delta Modulated DC-DC Converters (2021)
Presentation / Conference Contribution
Pena-Quintal, A., Niewiadomski, K., Greedy, S., Sumner, M., & Thomas, D. (2021, September). The Influence of the Number of Frequencies and the Frequency Repetitions Rates in Spread Spectrum Sigma-Delta Modulated DC-DC Converters. Presented at 2021 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC), Nusa Dua - Bali, Indonesia

This paper explores the impact of using a Spread Spectrum modulation technique based on a Sigma-Delta modulator for a DC-DC SiC-based power converter. A simple block is proposed for the PWM to generate square pulses close to 20 kHz with a controlled...

We have previously reported that low-intensity microwave exposure (0.75-1.0 GHz CW at 0.5 W; SAR 4-40 mW kg-1) can induce an apparently non-thermal heat-shock response in Caenorhabditis elegans worms carrying hsp16-1::reporter genes. Using matched co... Read More about A small temperature rise may contribute towards the apparent induction by microwaves of heatshock gene expression in the nematode Caenorhabditis elegans.
