Latest Patents

One of his latest patents is a rotary electrical machine with improved power electronics. This invention primarily focuses on a rotary electrical machine designed for motor vehicles. It includes a device for controlling a regulator of a motor vehicle alternator, along with an alternator that comprises the corresponding regulator. The regulator features a circuit that generates an activation command by elevating a bidirectional line to a first voltage that exceeds a high reference voltage. This line is connected to a detection circuit that monitors the status of the activation command. The detection circuit is equipped with generation means that produce a fault signal based on a flag indicating a failure of the alternator. This process links the line to ground through a switching element, thereby reducing the line to a second voltage that is lower than a fault voltage, which is still below the high reference voltage. The control circuit is designed to detect the fault signal and transmits a setpoint PWM signal with a maximum voltage higher than the high reference voltage and a minimum voltage lower than a low reference voltage, which is above the fault voltage. The duty ratio of this setpoint signal is representative of a setpoint voltage of the regulator.
