Effects of thermal aggressions on susceptibility responses and immunity figures of PWM patterns

Abstract

Abstract-In embedded and on-board electronics context, environmental temperature has an influence on the real electromagnetic compliance and EMC figures. We present studies and results of temperature impacts on susceptibility and immunity figures. Specific dual thermal-electromagnetic set-up have been developed for this. A campaign of EMC-Thermal-parametric measurements has been realized on PWM patterns of digital PCBs dedicated for electronic drive and command. Temperature dependent susceptibility behaviors are presented, in the range of 3GHz for harmonic aggressions, that leads to discuss of new cases of EM sensitivity, couplings and immunity approach on electronic devices.
