摘要： A starting apparatus for a direct current (DC) brushless motor and a method thereof are provided. The DC brushless motor comprises a plurality of windings presenting a joint connection via a common connection. The starting apparatus provides current to two of the three windings and rotates the DC brushless motor to obtain a Back Electro-Motive Force (BEMF) from the floating winding. Then, the starting apparatus provides a current to another two windings to operate the motor according to the variation of BEMF induced by the swing of the motor when it rotates to a static equilibrium point.

摘要： The present invention discloses a brushless dc motor driver circuit capable of reducing vibration or shock noise and a method thereof. The brushless dc motor driver circuit of the present invention comprises a Time-Voltage Digital/Analog Converter. The Time-Voltage Digital/Analog Converter further comprises: at least one magnetic field detecting circuit, at least one counter, and a signal processor. The Time-Voltage Digital/Analog Converter is connected to a driver circuit of a brushless dc motor and detects the periodically varying magnetic field of the brushless dc motor. Based on the rising time and the falling time of the preceding magnetic field variation, the Time-Voltage Digital/Analog Converter calculates the elapsed time from the current phase-change point and generates a linearly rising signal and a linearly falling signal. Then, those two sets of analog signals are used to drive the brushless dc motor. Thereby, the vibration or shock noise of the brushless dc motor is reduced. Besides, the phase switching rate of the brushless dc motor can be modified via adjusting a first magnetic flux density and a second magnetic flux density of the Time-Voltage Digital/Analog Converter.

摘要： The control circuit for power supplying includes a driving module and a control module, wherein the driving module includes a first switch, a second switch, a third switch, and a fourth switch. In a first power supply mode, the first switch and the second switch are turned on, and the third switch and the fourth switch are turned off. The load current flows to the ground terminal via the first switch, the inductive load, and the second switch. When the control module sends a switching signal to the driving module, the first switch and the second switch are turned off and the third switch and the fourth switch are turned on, and the load current flows to the high potential terminal via the fourth switch, the inductive load, and the third switch due to the current inertia.
