FIELD: electricity. ^ SUBSTANCE: invention refers to schemes of controller for hot swapping, in which there used is external current-limiting transistor, and describes electric circuit (100), method and computer program for hot swapping of electronic board in communication system; at that, current increase in electric circuit is controlled by means of microcontroller (130) switching the power transistor in circuit (150) for current switching so that the voltage of capacitor for electronic board can be gradually increased. Rate of current is measured either in microcontroller (130) itself, or in external circuit (140) for current monitoring, and compared to maximum rate of current. ^ EFFECT: providing flexibility, low cost and easy configuration. ^ 34 cl, 2 dwg |
