ABSTRACT:
Disclosed is a power supplying circuit for a ceiling fan including a protecting unit, a power supplying unit and a rectifying unit. An operation of the power supplying circuit is divided into four cases which are a negative half cycle loop, a positive half cycle loop, a control loop and a protection loop. Using this power supplying circuit, a stable DC voltage output can be achieved for both a control purpose and a detection purpose when a load being in a series connection with the power supplying circuit varies from a low load to a high load.
