Simulation of a Boost Converter for the Automotive Industry

The paper describes an analyze and a simulation comparison between 2 types of coils for a DC-DC boost converter. The analysis of the circuit is realized with two different types of software which have the same method of compilation. The presented study was used as a reference point for the integrated circuit (IC), ISL “78227”, circuit that has been used in the series production for automotive industry projects, especially as a boost converter driver. The DC-DC boost converter was designed to rise up the voltage from Vin=9V up to Vout_1=50V and Vout_2=55V. During the simulation, the main focus stayed on the circuit design within two simulation software and also on the component parametrization in according with the components that were taken in consideration within the project requirements. Nevertheless, the paper presents the results that were obtain after the simulation and also shown both variants of the output voltage in according with the project requirements. The work contains also a comparison between the functionality and the malfunction of the system for the 2-phase usage of the boost converter.
