Abstract: A dual-switch flyback power converter includes a control circuit to generate a switching signal. A high-side driving circuit includes a pulse generation circuit. The pulse generation circuit generates a pulse-on signal and a pulse-off signal to control two transistors in response to the switching signal. The two transistors further respectively provide a level-shift-on signal and a level-shift-off signal to a comparison circuit to enable/disable a high-side driving signal. Without using a charge pump circuit to power the high-side driving circuit, a floating winding of a transformer is utilized to provide a floating voltage to power the high-side driving circuit, which reduces the cost of the dual-switch flyback power converter and ensures a sufficient high-side driving capability of the high-side driving circuit.

Abstract: A BLDC (brushless direct current) motor system of the present invention includes a control circuit, a sequencer, a driving circuit, and a BLDC motor. The control circuit determines the maximum torque and the maximum speed of the BLDC motor. The control circuit includes an over-current detection circuit to generate a reset signal in response to a switching current of the BLDC motor. The reset signal is generated when the switching current of the BLDC motor exceeds a threshold. A pulse width of the PWM signal is correlated to the level of a speed-control signal and the level of the torque-control signal. The pulse width of the PWM signal is also controlled by the reset signal generated by the over-current detection circuit.

Abstract: A method for confirming correctness of a signal includes: providing a current to flow through a time-dependent impedance circuit, wherein the time-dependent impedance circuit provides at least two resistances at two different time points, the current flowing through the time-dependent impedance circuit to generate a first voltage at a first time point, and the current flowing through the time-dependent impedance circuit to generate a second voltage at a second time point, the first voltage and the second voltage being different from each other. When a predetermined relationship exists between the first voltage and the second voltage, it is confirmed that a signal provided from a node coupled to the time-dependent impedance circuit is correct.
