<p>A device (1) is provided for preventing high voltage from acting on a load (3) driven by a bicycle dynamo (2). The device comprises a sensor circuit (5) and a control circuit (6). The sensor circuit (5) senses an operating signal derived from the dynamo (2), wherein the operating signal corresponds to a voltage generated by the dynamo (2). The sensor circuit (5) also provides a control signal when the operating signal passes a threshold value. The control circuit (6) is operatively coupled to the sensor circuit (5) and is adapted to be coupled between the dynamo (2) and the load (3) to control the current delivered to the load (3) in response to the control signal.</p> |
