A phase regulated power supply is provided for converting alternating current (AC) to direct current (DC) for powering a DC brushless motor, such as a fan. The power supply includes a full wave bridge rectifier and a driver circuit, which may be an IC chip, controlled by standard commutation circuitry. An output capacitor is connected electrically downstream to the switch for supplying a reduced DC ripple voltage to the motor load. The power supply preferably includes a line filter for removing input power surges. The speed of the motor may be varied by ...


A phase regulated power supply to be contained in the housing of a DC brushless motor for converting alternating current (AC) to direct current (DC) to power the motor, the power supply comprising: interrupting means for periodically interrupting an AC line source to rectify and regulate voltage from the AC line source to provide DC current for the motor, the interrupting means to be electrically coupled downstream to said AC line source; a power converter stage having first and second input terminals, the power converter stage being coupled electrically...
