ABSTRACT:
An anti-false triggering system for a pulse width modulation system includes a ramp generator for generating a ramp signal having a ramp portion and a rest portion; a latch enable signal generator for providing a latch enable signal only during the ramp portion of the ramp signal; and a pulse edge modulator responsive to the ramp portion of the ramp signal for providing a pulse with at least one of its edges modulated, the pulse edge modulator being enabled by the latch enable signal only during the ramp portion of the ramp signal for suppressing false triggering of the pulse edge modulator during the rest portion of the ramp signal.
