Mitigating Electromagnetic Interference in Power Converters for Radio Astronomy Applications

Abstract

Computational studies and a prototype half-bridge DC-DC converter capable of logistic-shaped switching transitions to achieve high-frequency electromagnetic interference mitigation is presented. The logistic-shaped transition provides steep spectral content roll-off, which is desirable for low noise outcomes. The research demonstrates that shaped switching transitions can be integrated into power converters operating with pulse with modulation control strategies, which is desirable for low noise applications such as radio astronomy.
