ABSTRACT:
A signal generating apparatus for generating a first pulse width modulation (PWM) signal and a second PWM signal synchronous with the first PWM signal, the first and second PWM signals controlling a switching power supply having a transformer with a plurality of secondary windings. The on-widths of the first and second PWM signals are adapted to be controlled independently, and the on-width of the second PWM signal is adapted to be increased or decreased without being affected by an increasing/decreasing state of the on-width of the first PWM signal. To this end, when the on-width of the second PWM signal is increased or decreased, the data used for increasing or decreasing the second PWM signal is corrected in accordance with the change state of the on-width of the first PWM signal.
