Title:
PWM SIGNAL GENERATOR AND LIGHTING CONTROL APPARATUS HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2018/124670
Kind Code:
A1
Abstract:
A PWM signal generator and a lighting control apparatus having the same are disclosed. The PWM signal generator according to one embodiment of the present invention comprises: a first comparison unit for comparing a duty value being inputted with a reference wave being inputted to output a first PWM signal; a signal inversion unit for inverting the duty value being inputted on the basis of a maximum value of the reference wave; a second comparison unit for comparing the duty value inverted by the signal inversion unit with the reference wave being inputted to output a second PWM signal; and a reference wave generator for generating a reference wave to transmit the same to each of the first comparison unit and the second comparison unit.
