Title: Stefano Saggini: Power Electronics and Half-Bridge Driver Innovations

Introduction

Stefano Saggini is an inventor based in Udine, Italy, whose patent work focuses on power electronics and control circuits. His portfolio includes 2 patents, including inventions related to half-bridge drivers and power-stage control.

Latest Patents

One of Saggini’s patents describes a half-bridge driver circuit that controls switching between two field-effect transistors (FETs). The circuit detects when current through the first FET reaches a threshold, then switches the first FET off and the second FET on. Its control system combines a proportional-integral error amplifier with slope compensation, using sampled current information to determine the switching threshold.

Another patent concerns a driver circuit for a power stage containing parallel FETs. It compares signals representing the reference FET’s driving and conduction losses to adjust a reference current. The circuit then uses that current and sensed power-stage current to generate enable and drive signals for the individual FETs.
