Abstract: A method is for reducing pulse skipping from a characteristic affecting a modulating signal input to an integrator of a pulse width modulation (PWM) modulator, together with a square wave carrier signal for generating a triangular waveform of the PWM modulator. The method may include creating a broad synchronous peak at vertexes of the triangular waveform output by the integrator.

Abstract: A power electronic device includes first and second electronic switches, each integrated on a package having a low parasitic inductance, a supply terminal and a ground terminal. The first conduction terminal of the first switch may be coupled with the supply terminal, and the second conduction terminal of the second electronic switch may be coupled with the ground terminal. The corresponding control terminals of the switches may be coupled to corresponding pilot drivers. The package may include first and second electric terminals, wherein the second conduction terminal of the first switch is coupled to the first electric terminal, and the first conduction terminal of the second switch is coupled to the second electric terminal. A first inductance may be interposed between the first electric terminal and the output terminal and/or a second inductance interposed between the second electric terminal and the output terminal.
