摘要： A starting-process controller for starting a piezomotor, having a voltage-controlled oscillator, a power output stage, and a resonant converter. The oscillator generates the control signals required for the power output stage and the resonance converter converts the stepped output voltage from the power output stage into a sinusoidal voltage at the output. The resonance converter drives the piezomotor with the voltage. The motor current that flows when the piezomotor is driven is measured and compared with the phase of the drive voltage in a phase comparator. The comparison output signal is a measure of the phase difference at the time between current and voltage. A phase-locked loop filter smoothes the phase-difference signal for controling the oscillator. The controller includes a start-assisting circuit element that fixes the output voltage from the phase-locked loop filter at start-up and thus applies a constant voltage to the input of the voltage-controlled oscillator.

摘要： The present invention relates to a method for controlling an illumination device (100), the illumination device (100) comprising a flux sensing unit (101) and at least two differently colored light sources (102, 103, 104), the method comprising the steps of switching on and off each of the light sources according to a predefined pattern, acquiring measurement values by means of the flux sensing unit at predetermined intervals in accordance with the predefined pattern, calculating a color point for each of the light sources based on the measurement values, calculating a difference between the color points and corresponding reference color points, and adjusting an analog current drive level of the light sources, wherein the difference is minimized such that a desired color is obtained. The present invention provides for the possibilities to in a more accurate way correct for the color changes due to change in drive current, temperature, and aging effects. Furthermore, the control method according to the present invention does not require a factory calibration, or knowledge of batch specific binning information, for obtaining the current or temperature related characteristics of the light sources, which significantly reduces the cost normally related to factory calibration and batch specific binning information. Furthermore, the present invention relates to an illumination device (100) comprising means for performing such a method.
