Disturbance Property of High-frequency Transformer Model for Photovoltaic Applications

This paper investigates disturbance property of noise source and performance of propagation path for small-scale photovoltaic applications using a pulse transformer. A detailed high-frequency (HF) model taking into account parasitic components is used to consider the decoupling effect of common-mode and differential-mode noises pass through it. Based on simulation results, leakage current and electromagnetic compatibility issues are clarified following actual operation conditions.
