Latest Patents
Gianfranco Perna holds 1 patent for his invention titled "Controller for a three-phase brushless D.C. motor." This patent describes a controller that features a full bridge circuit and an electronic control unit (ECU). The full bridge circuit consists of three branches, each equipped with switches connected to the motor windings. The switches are activated by signals from the ECU, which are organized into two sets of three signals. These sets are offset by 180 electrical degrees, while the drive signals within each set are offset by 120 electrical degrees. The active portion of these drive signals includes an initial interval of pulsed activation, an intermediate interval of continuous activation, and a final interval of pulsed activation. Notably, the active portion exceeds 120 electrical degrees, with overlapping intervals of pulsed activation among the switches.
