| 摘要 |
The invention relates to a power factor correction circuit (PFC) comprising a charging coil (LI) with which a storage capacitor is charged with discharge current by a controlled circuit (MI). Said circuit (MI) is switched on and off by an electronic control and regulation device which detects, on an inlet, directly or indirectly, the current through the circuit (MI) at intervals when the circuit (MI) is closed, and detects an additional operational parameter of the boost PFC circuit at intervals when the circuit (MI) is open. |
