Three-phase synchronous rectifier for charging a battery on board the vehicle

A three-phase synchronous rectifier for charging a battery on board a vehicle, the three-phase synchronous rectifier comprising:

• a first and a second input which are independent of each other and each connectable to a respective first and second three-phase output branch of a generator;
• two independent negative and positive outputs each connectable to the respective poles of said battery;
• a first group of three rectification units configured to be connected to said first output branch of said generator by means of said first input;
• and
• a second group of three rectification units configured to be connected to said second output branch of said generator by means of said second input,
• a limitation block operationally connected to a current limiting circuit to limit a maximum output voltage in case of battery disconnection, wherein the connection between said limitation block and said current limiting circuit is made by means of a zener diode operating at a voltage ranging from 18 to 21 Volts:
• wherein
• said rectification units are configured to be simultaneously connected to the battery of said vehicle.
