Description
Summary:The paper presents the results of research on the influence of the type of power supply for the 1986BE91T microcontroller on its radiated emissions in the TEM cell. The emission measurement results are given when power is supplied to the measuring printed circuit board (PCB) with microcontroller from a pulse power supply unit, mains chargers and power banks, USB-port of PC, as well as a rechargeable battery. It is shown that it is advisable to use a rechargeable battery to minimize radiated emission from the power supply circuits of PCB.
