Sectioned linear transformation method

The invention discloses a sectioned linear transformation method which is implemented by firstly utilizing a comparer to receive a sectioned linear triangular wave signal that has at least three sections of wave forms with different slopes and a reference signal, and then transforming the reference signal according to the voltage point where the triangular wave signal and the reference signal interlaced as well as the change of the slopes of the triangular wave signal so as to output a pulse width modulating signal. The invention can reduce the distortion degree of saturation signals of general D class power amplifiers during digital signal transformation.

Power factor correcting device and correcting method thereof

The invention discloses a power factor correcting device and a correcting method of a power factor. The power factor correcting device and the correcting method of the power factor keep that an input current is in a simple sinusoidal alternating current form and keeps the input current shares the same phase with an input alternating voltage. An alternating voltage is converted into a full-wave rectification form through a full-bridge rectifier, and is converted into a direct current output voltage through an inducer, a power transistor and a power diode. A current compensating circuit and a voltage compensating circuit respectively generate a compensating current signal and a compensating voltage signal after respectively comparing a correcting current and an output voltage respectively with a reference signal and a reference voltage, and an updated pulse width modulation signal is generated according to the compensating current signal and the compensating voltage signal. The reference current signal is obtained through multiplying the compensating current signal by the compensating voltage signal through a multiplication gainer, so that the input current can be corrected without the needs of sampling an input voltage according to the technology, and response speed of an internal circuit is improved.
