| Abstract |
Magnetic components are an important part of many DC/DC converters. The use of active premagnetization makes them adjustable, which means an additional degree of freedom in the design of the respective converter topology. However, when selecting the most suitable premagnetization method for the specific application, various impact factors should be taken into account to ensure an optimal design.This paper presents, analyzes and discusses impact factors such as the adjustability range of the inductance value, the magnetic feedback as well as the behaviour of the auxiliary circuit for different premagnetization methods and different inductor design approaches. The measurement verification was carried out using a buck converter. |
