This article introduces a novel methodology and experimental setup for measuring iron loss under pulsewidth-modulated power supply using a silicon carbide-based power converter to achieve high switching frequencies. The research aims to determine the influence of PWM and inverter parameters on iron losses and establish the required methodology for measurement and data processing.
This article presents a novel methodology and experimental setup for measuring iron loss under pulsewidth-modulated (PWM) power supply using a ring sample of the ferromagnetic laminated core. A power converter based on silicon carbide technology was used to achieve high switching frequencies and near ideal output voltage. The unique feature of the proposed setup is iron loss measurement under dc magnetization bias using a single excitation winding supplied by the single-phase inverter. The research objective is to determine the influence of PWM and inverter parameters on iron losses and to establish the methodology for measurement and data processing required to produce loss data maps that can be used to improve the accuracy of the total loss estimate for an electrical machine.
