  • Publication number: 20210199468
    Abstract: An encoder and a signal processing method are disclosed. The method includes: receiving an analog signal, and generating a filtered analog signal by an analog filter according to the input signal and a first frequency indication signal; generating a digital signal by an analog-to-digital converter according to the filtered analog signal; generating a filtered digital signal by a digital filter according to the digital signal and a second frequency indication signal; generating a seventh signal and an eighth signal by a dynamic offset calibration unit according to the filtered digital signal and a period indication signal; and generating a position information by a position detection unit according to the seventh signal and the eighth signal. The first frequency indication signal, the second frequency indication signal and the period indication signal are generated by a frequency generation module according to the filtered analog signal or the digital signal.

  • Patent number: 9257896
    Abstract: A control circuit of a power converter including a first and a second control modules is provided. The first control module sets sampling points for a ripple signal of an input voltage according to a reference signal. The first control module determines whether a power point is the maximum power point according to ripple voltages of the sampling points. The second control module controls the power converter to output a maximum power according to the maximum power point based on the determination result of the first control module and the reference signal. An embodiment of a method for tracking a maximum power point is provided. The input voltage of the power converter is measured. The sampling points are set for the ripple signal of the input voltage and phase information of the ripple signal is determined, such that the maximum power point is determined by using the ripple voltages.
