Calculations Of Nonisothermal Characteristics Of DC-DC Converters With The Average Models Taken Into Account

Abstract

In the paper a new method of an electrothermal analysis of DC-DC converters operating in the steady-state is proposed. This method is based on the elaborated by the authors' electrothermal average model of the diode-transistor switch. This model was verified by comparing SPICE simulated characteristics of the buck and boost converters operating both in the continuous and discontinuous conducting mode obtained by the proposed method and the electrothermal transient analysis
