Latest Patents

Among his notable creations, two recent patents stand out:

1. **Method and Device for Controlling an Alternator-Starter of a Motor Vehicle**

This invention introduces a unique method for controlling the inverter of an alternator-starter. The alternator-starter comprises phase windings connected to an inverter linked to an onboard electrical network powered by a battery. The method operates in two modes, depending on the rotational speed of the alternator-starter. Specifically, it utilizes a chopped full-wave control mode when the speed is below a designated threshold and switches to a full-wave control mode when above it. The transition between these modes is managed through a hysteresis cycle using two predefined threshold speeds.

2. **Signaling Method and Device for Impaired Function of an Electronic Power System in a Multiple-Phase Alternator**

This signalling method is crucial for enhancing the reliability of electronic power systems in multiple-phase alternators. It involves a set of rectifiers capable of rectifying voltage from the produced phases and a control assembly that monitors current characteristics against nominal standards. Should any non-conformity be detected, the method provides a way to simulate these issues, ensuring that existing signaling means are utilized effectively to indicate additional impaired functions.
