“…Many studies are available in the literature on the effect of temperature on electronic equipment. In [18][19][20][21][22] it is highlighted that capacitors and MOSFET are the most sensitive components to thermal drift. On the other hand, in [2,3] it is shown that inductors are more affected by humidity than temperature.…”

“…It describes the maximum change in capacitance over a specified temperature range and it is usually expressed as ppm/K. The behaviour of ceramic capacitors depends on their dielectric material [22]. The two main standards regarding (C,C 1 ), which allow to satisfy (8) and (9) these technologies are the International Electrotechnical Commission (IEC) standard IEC/EN 60384-1 [23] and the IEC/EN 60384-8 [24].…”

In this study, a procedure to evaluate the performance of a power converter under different operating conditions is presented. The technique takes into account the effect of the environmental conditions and the tolerance on each component and it provides a probability estimation that the converter will reach certain performance under definite operating condition. This feature allows to better understand the operation of the converter even outside the nominal operating conditions. Furthermore, by appropriately modelling the performance of each component, it is possible to understand from the early design stages which component technology is more suitable according to the environment in which the converter will work. The steps of the procedure are explained in detail and a case study applied on a Class-E inverter to provide a step-by-step explanation and to experimentally validate the accuracy of the probability estimation is presented. General description of the proposed method Depending on the field of application of a PC defined levels of performances are required. These performances can be described by M functions f j with j = 1, 2, …, M, each one representing a parameter of interest of the PC. Typical performance functions can
