Abstract

The utility model relates to a ceiling fan controller with the functions of speed regulation, timing and remote control. A power switch, a rectifier, a main controlled silicon, a main power supply (a diode series), etc., in the main control circuit which pass through an alternating current main loop of the controller are connected in series. A speed regulation circuit generates a pulse signal with adjustable duty ratio, and the pulse signal acts on the grid electrode of the main controlled silicon to control the switching on and switch off. When the main controlled silicon is switched on, alternating current voltage form a passage (the main loop) to cause the ceiling fan to obtain electricity to ahcieve operatio. N when the main controlled silicon is switched off, the ceiling fan is powered off, but operates for inertia. The speed of the ceiling fan can be changed by changing the break-make ratio of the main controlled silicon in unit time. The on and off of the main power supply can be controlled by a pulse output by a timing circuit and a remote control circuit. When the main power supply is switched on, the speed regulation circuit obtain electricity to cause the ceiling fan to achieve normal work. When the main power supply is switched off, the speed regulation circuit lose electricity to cause the ceiling fan to stop working. The additional functions such as timing, remote control, etc., can be achieved.
