Thermal Analysis of Power MOSFETS in Boost DC/DC Converter

Abstract

When designing power electronics, there is almost always a problem of ensuring acceptable thermal operating modes of components. Optimization of the heat dissipation of the designed device leads to an increase in the service life of components and the design as a whole. This article discusses methods that allow you to anticipate and eliminate the problem of heat generation of the most critical components, as well as the overall design already at the design stage of the device. The analysis is performed on the example of a synchronous pulse stepup DC / DC converter designed for the automotive industry. This approach allows you to significantly reduce the cost of developing a finished product.
