专利汇可以提供Battery charging systems for road vehicles专利检索,专利查询,专利分析的服务。并且A battery charging system for a road vehicle has a three phase permanent magnet alternator for charging the battery through a full wave rectifier. Thyristors are associated with the full wave rectifier for controlling the supply of power from the alternator to the battery, conduction of the thyristors being determined by a voltage regulator coupled to the battery. The rectifier consists of four thyristors and two diodes, the two diodes being associated with one phase of the alternator and the four thyristors being associated with the other two phases of the alternator. If a voltage surge occurs as a result of the battery being disconnected, then means operate to ensure that gate current is removed from the thyristors to ensure that the thyristors turn off.,下面是Battery charging systems for road vehicles专利的具体信息内容。

1. A battery charging system including a three phase permanent magnet alternator for charging the battery through a full wave rectifier, thyristors associated with the full wave rectifier for controlling the supply of power from the alternator to the battery, and a voltage sensitive control circuit controlling the gate current supplied to the thyristor to regulate the output voltage of the alternator, in which the full wave rectifier includes four thyristors and two diodes, the two diodes being associated with one phase of the alternator and the four thyristors being associAted with the other two phases of the alternator, the voltage-sensitive control circuit providing gate current to the four thyristors when the rectifier output voltage is below a predetermined value, and removing the gating current when the rectifier output voltage is above the predetermined value, the system further including delay means for sensing a voltage surge caused by disconnection of the battery, and for ensuring that in these circumstances gate current is removed from the thyristors for a predetermined period of time sufficiently long to ensure that the thyristors turn off.
2. A system as claimed in claim 1 including a Zener diode connected across the output of the rectifier, said Zener diode limiting the amplitude of said surge during said predetermined period of time.
3. A system as claimed in claim 1 in which said diodes are Zener diodes, said Zener diodes limiting the amplitude of said surge during said predetermined period of time.
