Abstract

Conventional constant-power design methods for magnetic components tend to result in oversized and inefficient solutions for pulsed power load applications. This manuscript introduces an innovative framework that categorizes magnetic components according to the correlation between the application's pulse period and the component's thermal time constant τ. Three distinct design categories are established using a thermal/electrical equivalent model: average power, oscillating temperature, and peak power magnetics. The classifications are integrated into a multivariable optimization process to produce Pareto fronts representing total volume against power loss for diverse PPL applications, such as medical imaging and regenerative braking. The analysis suggests that designing for oscillating or peak temperatures can significantly enhance power density, leading to a reduction in component volume by as much as two orders of magnitude compared to traditional designs. This framework offers a systematic method for application-specific PPL magnetic design, marking an essential advancement toward establishing a standardized methodology similar to the IEC 60034-1 duty-cycle classifications for electric motors.
