Investigating The Effect of Environmental Parameters On The Reliability Of Power Supplies For Induction Heating Techologies

The present paper views the effect of a set of environmental factors which affect the reliability indicators of power supplies in induction heating technologies. Its aim is to make it possible, by combining two or more factors, to define the area where a specific supply force could operate at a particular reliability rate, as well as whether its reliability will considerably deteriorate if given indicators are exceeded. In previous studies it was established that not all correction factors used in the methods for calculating failure rates of electronic components reflected the exact operating conditions of the environment of a specific production unit. The introduction of such a correction factor and an empiric expression for it enables us to determine this factor in stationary mode. It is assumed that its value is defined by a specific value when environmental conditions do not change. Therefore, at the presence of dynamics or a change of those factors, this paper makes an attempt to synthesize a graphic solution which provides the admissible range of their change.
