Problems solved by technology

Therefore, when the voltage of the electric power stored in the storage element decreases when the actuator with large capacitance, such as a motor, operates, it may cause other electrical components such as the control device to fail to operate normally.
[0007] In addition, the sensor circuit that processes the signal from the sensor connected to the control device is often easily affected by noise.
For example, motors sometimes generate noise due to the sliding of brushes
Also, digital processing circuits tend to generate switching noise
If the power supply with such noise superimposed is supplied to the sensor circuit, it may cause malfunction of the sensor circuit

Abstract

A bicycle power supply comprises first and second storage elements 38a, 38 b structured to receive power arising from an AC power supply for supplying power to first and second electrical components, respectively. A power inhibiting unit 42 may be provided for preventing power from being communicated from the first storage element 38 a to the second electrical component and / or for preventing power from being communicated from the second storage element 38 b to the first electrical component.

Description

technical field [0001] The present invention relates to a power supply device, particularly a power supply device for a bicycle that stores electric power of an AC generator mounted on a bicycle and supplies electric power to a first electrical component for driving an actuator and other second electrical components. Background technique [0002] In recent bicycles, there are forms in which electrically controllable electrical components such as a shifting device, a suspension, or a display device, or electrical components such as a control device are used. For example, there is a known technique of installing a speed sensor to quickly and automatically shift the speed of a bicycle gear in accordance with the speed. [0003] A bicycle using such an electrical component must have a power supply unit for supplying power to a display unit, a control unit, or a shifting unit. Such a conventional power supply device for a bicycle uses a battery, and operates an electrical compon...
