Investigation and Prediction of High-Frequency Iron Loss in Lamination Steels Driven by Voltage-Source Inverters Using Wide-Bandgap Switches

Le Chang et al.

Summary: This article experimentally characterizes the magnetic and iron loss properties of lamination steels excited by a voltage-source inverter using GaN-based WBG switches, and develops a new J-A model for PWM-induced iron loss analysis. The model is integrated with a dynamic hysteresis model to provide an accurate and efficient tool for total iron loss estimation during PWM voltage excitation using high-frequency WBG devices. Experimental verification of the model accuracy and investigation of the impact of elevated fundamental frequencies and field amplitudes on total iron loss are conducted.
