ABSTRACT:
A System for generating a PWM output voltage signal include a first half bridge having a first set of switches, and a second half bridge having a second set of switches. A control unit is configured to generate a first PWM switch-signal for switching the first set of switches; to generate a second PWM switch-signal for switching the second set of switches; and to vary at least one of pulse widths and phases of the first and second PWM switch-signals relative to each other for varying a pulse width of a PWM output voltage signal so that the PWM output voltage signal equals zero when the pulse widths of the first and second PWM switch-signals are equal to each other.
