Abstract

The invention relates to electronics and can be used in direct current sources with accumulators as a direct current switch on and off device and as an accumulator discharge protection device.The accumulator switching and protection device comprises a bipolar transistor (V1) with p-n-p structure, parallel to its emitter-base junction being connected a resistor (R1), the emitter of transistor (V1) is connected to the “plus” terminal of an accumulator (Ac), and the collector - to the output terminal (“+ Uieş”) and the base, through a resistor (R2), - to the collector of a bipolar transistor (V2) with n-p-n structure, connected with the emitter to the “minus“ terminal of the accumulator (Ac), connected to the output terminal (“-Uieş”), and with the base, through a resistor (R3), - to the collector of transistor (V1), at the same time the base of the transistor (V2) is connected to the collector of a bipolar transistor (V3) with n-p-n structure, connected with the emitter to the “minus“ terminal of the accumulator (Ac), and with the base, through a resistor (R4), - to the “minus“ terminal of the accumulator (Ac) and, through a resistor (R5), - to a control terminal (“Input”), connected to a microprocessor connected in parallel to the accumulator (Ac). The device further comprises two switches (B1) and (B2), connected in parallel, respectively, to the collector-emitter and base-emitter junctions of transistor (V2), and a capacitor (C1), connected in parallel to the accumulator (Ac).
