Abstract
The present invention relates to a supply circuit having a storage capacitor, including, across a rectifying bridge, a storage capacitor associated with a charge path and with a discharge path, the charge path including a current limiter on a determined value and controllable according to the voltage across the rectifying bridge and to the voltage across the storage capacitor, whereby the storage capacitor charges with a substantially constant current during each of its charge phases.
Claims11
A supply circuit having a storage capacitor, including, across a rectifying bridge (1), a storage capacitor (C1) associated with a charge path and with a discharge path, characterized in that the charge path includes a current limiter (10, 10') on a determined value and controllable according to the voltage across the rectifying bridge and to the voltage across the storage capacitor, whereby the storage capacitor (C1) charges with a substantially constant current during each of its charge phases.
