Analysis and design of package-integrated galvanically isolated power converter with high coreless transformer working voltage

Abstract

Galvanic isolation is an important safety consideration for electrical systems. As the demand for circuits that make use of higher voltages increases, the demand for better isolators follows, and an important metric for determining the strength of an isolator is its working voltage. Ensuring that systems with higher working voltages can maintain respectable efficiency and power delivery is of equal importance. This project aims to design an integrated DC-DC converter with a working voltage as high as 1500Vrms, while also delivering at least 500mW output power with at least 30% efficiency. This will involve an iterative design process to select an oscillator, isolator, and rectifier that will demonstrate the feasibility of this converter in simulation.
