Abstrakt:	We propose the algorithm to determine the power supply to the printed circuit board electronic components from real-time analysis of trends in the readings of built-in temperature sensors. The algorithm is based on the consistent application of two linear regressions and contains two parameters. The details of the impact of these parameters on the accuracy of power determination is discussed. The algorithm is verified on data obtained from a multifunctional laboratory test bench. The test bench simulates the operational conditions of printed circuit boards that are close to the onboard spacecraft conditions. The central part of the laboratory test bench is a thermal simulator of a single printed circuit board with a built-in temperature sensor system. The efficiency of the algorithm is shown so it can be applied in the the conditional monitoring. [ABSTRACT FROM AUTHOR]
