DISPOSITIVO ELETTRONICO DI TAMPONE PER L'ALIMENTAZIONE DI APPARATI E- LETTRICI ED ELETTRONICI

The device according to the invention is used for the power supply of electric and electronic apparatus, in which at least two electric power supplies, for example, two electric batteries B1, B2, are electrically connected - directly or through respective electric or electronic interrupter devices I1, I2 - in an electric circuit for the electrical power supply of an electric or electronic consuming device D1, for which it is desired to prevent malfunctioning due to outage of electric power supply. This involves, according to the invention - in electrical connection in said electrical circuit (connections C1, C2, C4) - electronic connector means R1, which electronically connect said at least two electric power supplies with respect to said electric or electronic consuming device, furnishing to said consuming device an electrical voltage that is equal to the logical sum of the electrical voltages of said power supplies, preventing a short circuiting of either of the power supplies from interfering with the other one or other ones, so that, in normal operating conditions, the electric power put out is shared uniformly among said power supplies, while in conditions of malfunction of at least one power supply the still operating power supply or power supplies furnish the full electric operating power necessary for said consuming device.
