ELECTRONIC CHALLENGE WITH TWO SPANISH PROVISIONS

摘要

An electronic circuit is described. The electronic circuit includes: an output (OUT),who is trained to be connected to a load (Z); and a first supply circuit (11) and a second supply circuit (12),which are connected to the output (out) respectively. The first supply circuit (11) and the second supply circuit (12) each include one supply input (IN1, IN2),trained to obtain a given input voltage (VIN1, VIN2); a first circuit node (N11, N12);a first electronic switch (S11),which is switched between the output (OUT) and the first switching nodes (N11, N12); a first alignment element (D11, D12),switched parallel to the first electronic switch (S11, S12); at least one second electronic switch (S21, S22; S211, S212, S221, S222),which is switched between the supply input (IN1, IN2) and the first switching node (N11, N12); at least a second alignment element (D21, D22; D211, D212, D221, D222),which is switched parallel to at least one second switch (S21, S22; S211, S212, S221, S222), with at least one second rectifier element (D21, D22) and the first rectifier element (D21, D22) antiserially switched to each other; and a control switch (21, 22). The control circuit (21, 22) is designed to control the first switch (S11, S12) and the second switch (S21, S22) and to obtain a supply voltage (VN11, VN12) from the first circuit node (N11, N12) at a supply entrance (231, 232).
