초록 ▼

A method is provided for controlling power generation. A control circuit is employed to control first and second switches of each of multiple switch groups of a drive circuit so that the first switches are kept in OFF state while the second switches are each switched between ON and OFF states at each given time point. With the second switches of the switch groups alternately switched ON/OFF, electrical power is fed to a circuit system, which includes a power storage device or an application device of loading.

1. A method for controlling power generation, comprising a drive circuit and a control circuit, the drive circuit receiving a control signal from the control circuit, the drive circuit comprising at least two groups of switch, which are connected in parallel to each other, each group comprising a first switch and a second switch, which are connected in series with each other, a kinetic mechanism that comprises rotor, stator, and magnetic field having phases each of which is connected between the first and second switches of each group, at least one rotor position detection element arranged to detect position signals of the rotor, the switch groups being each electrically connected to a circuit system, wherein the method for controlling power generation comprises the following steps: each of the second switches being subjected to pulse width modulation for ON/OFF switching according to the position signals of the rotor, and each of the first switches remaining OFF. 2. The method according to claim 1, wherein the switch that is subjected to pulse width modulation for ON/OFF switching is switched ON/OFF at a time when a back EMF of a corresponding coil enters a high voltage zone, the high voltage zone being a high voltage zone of an upper half wave of voltage wave, the switching being set ON at an angular position of [180°−(360°/phase number)]/2 of the upper half wave and OFF at an angular position of 180°−{[180°−(360°/phase number)]/2}. 3. The method according to claim 1, wherein the switch that is subjected to pulse width modulation for ON/OFF switching is switched ON/OFF at a time when a back EMF of a corresponding coil enters a high voltage zone, the high voltage zone being a high voltage zone of a lower half wave of voltage wave, the switching being set ON at an angular position of {[180°−(360°/phase number)]/2}+180° of the lower half wave and OFF at an angular position of {180°−{[180°−(360°/phase number)]/2}}+180°. 4. The method according to claim 1, wherein a current detection element and a current signal shifting circuit are employed to detect and shift a negative current signal generated by the drive circuit so as to convert the negative current signal into a positive current signal. 5. The method according to claim 1, wherein the kinetic mechanism comprises rotor, stator, and magnetic field is an electric motor. 6. The method according to claim 5, wherein the electric motor controls an electric torque thereof through control of electrical current generated. 7. The method according to claim 1, wherein the kinetic mechanism that comprises rotor, stator, and magnetic field is an electric generator. 8. The method according to claim 7, wherein the rotor of the electric generator is driven by a force input device for rotation.
