摘要： A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED while the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilize the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.

摘要： Consistent with an example embodiment, there is a method of controlling a synchronous rectifier having an input signal having oscillations therein and a switch which is switchable between an open state and a closed state. The method comprises filtering the input signal to produce a filtered signal, comparing the filtered signal with a reference value, and opening the switch in response to the comparison, in which the filtering is active filtering.The active filtering may be based on determination of the peaks (positive and/or negative) of the signal, either directly, including a quarter period offset, or including decay—or a combination of the above; alternatively, the active filtering may be based on the a smoothing functions such as a switched low-pass filter or a short time integrator.

摘要： Method and apparatus for controlling the rotation velocity of an optical disc in a wide range of velocities, including low velocities. In a first range of velocities, a first sensor, for example an EMF sensor, is used to control the commutation moments of a turntable motor. For velocities outside the first range, a periodic control signal based on a periodic second signal generated by a second sensor and a mapping between the first and second periodic signal are used. The method and the apparatus are suitable for LightScribe™ applications.

摘要： The invention is directed to a method for controlling a deceleration process of a DC motor (20), wherein the DC motor (20) is driven by a bridge driver (18) coupled to a power supply (12) intended to provide a supply voltage VDD at a power supply output (14), the method comprising the following steps: applying a deceleration PWM signal to the bridge driver (18) for decelerating the DC motor (20), and controlling the bridge driver (18) such that a motor-induced back current is reduced, if the voltage at the power supply output (14) exceeds a first voltage threshold which is higher than VDD. In accordance with the invention the method comprises the following step: if the voltage at the power supply output (14) falls below a second voltage threshold which is lower than the first voltage threshold, terminating controlling the bridge driver (18) such that the motor-induced back current is reduced. The invention is also directed to a controller (10) for controlling a deceleration process of a DC motor (20) which is driven by a bridge driver (18) coupled to a power supply (12) intended to provide a supply voltage VDD at a power supply output (14), the controller (10) comprising: means (22) for applying a deceleration PWM signal to the bridge driver for decelerating the DC motor, and means (24, 26, 28; 24, 30) for controlling the bridge driver (18) such that the motor-induced back current is reduced, if the voltage at the power supply output (14) exceeds a first voltage threshold which is higher than VDD. In accordance with the invention the means for controlling the bridge driver (18) such that the motor-induced back current is reduced are adapted to terminate controlling the bridge driver (18) such that the motor-induced back current is reduced, if the voltage at the power supply output (14) falls below a second voltage threshold which is lower than the first voltage threshold.
