Electronic regulator for use with a cycle dynamo (G) or the like, and the invention is characterised in that the regulator (1) comprises two parallel-connected control circuits (TK1, TK2), each comprising a rectifier (D1, D2, D3, D4, respectively), one (D1, D2, D3) of which is adapted to admit only the negative voltage pulses and the other (D4) is adapted to admit only the positive voltage pulses from the generator, and each comprising a capacitor (C1 and C2, respectively) and each one voltage-sensing and one current-admitting device (T2, Ty1 and T3, Ty2, respectively), and that the respective voltage-sensing device (T2 and T3, respectively) is adapted to sense the charging voltage across the respective capacitor (C1, and C2, respectively) generated by each negative and each positive pulse, and further adapted at a predetermined voltage threshold, to open a current passage (Ty1, Ty2, respectively) in the respective control circuit, thereby to connect the dynamo to a current-consuming device (20), and to block the passage at crossover in the regulator, such that each negative and each positive pulse from the generator admits an amount of energy substantially proportional to the length of the opening time in the respective current passage. |
