  • Patent number: 11387824
    Abstract: A voltage-controlled varied frequency pulse width modulator is provided, including a frequency-regulating voltage output device which receives a determining voltage, decides a resonant frequency according to the determining voltage and outputs an oscillation signal having the resonant frequency. A duty-ratio-regulating voltage output device receives the oscillation signal and a reference signal to determine a duty ratio through an inverting closed loop, so as to adjust the oscillation signal to have the duty ratio. By employing the proposed voltage-controlled modulator circuit with tunable frequency and varied pulse width of the present invention, a modulation signal having the determined resonant frequency and duty ratio is obtained. Moreover, the present invention can be further combined with gate drive waveform trend feedback designs to achieve superior power transmission efficiency of a wireless power transmission system to optimize the inventive effect of the present invention.
