A development of MOSFET and IGBT thermal management in DC to DC converter

Abstract

This project was to produce a template of MOSFET and IGBT thermal management in DC to DC converter. Thermal management included by supplying variable input voltages to the DC to DC converter, and gets the variables of operating junction temperature, thermal resistance, and safety margin of operating junction temperature and power dissipation. According to the DC to DC converter circuit, the equations of the power dissipation is from the MOSFET and IGBT, then from the equations, the operating junction temperature, thermal resistance, and safety margin of operating junction temperature has calculated with respect to the variable input voltages. The technique that has been used is by varying the duty cycle of the MOSFET and IGBT. MathCAD 13 was used as the method of solution. This report highlights on how to get the variable thermal parameters by varying the input voltages.
