Abstract :
Hysteresis-based effective parameters (IeHys and AeHys) are described that are extracted from minor and major loop measurements, and are thus more suitable for computations involving these loops. For three commercial power ferrites, formulae are given for IeHys and AeHys of toroids with radius ratio kr between 0.2 and unity.
