Abstract

The present invention relates to a synchronous rectification generator and a protection method thereof. The synchronous rectification generator includes alternators, rectifier circuits, regulator circuits and controller circuits. An alternator having a field coil and a power generating coil section converts mechanical energy into alternating current power. The rectifier circuit converts AC power to DC power. The regulator circuit adjusts the field coil current. The controller circuit controls the rectifier operation of the rectifier circuit and detects if an abnormal event has occurred in the rectifier circuit. When an abnormal event occurs in the rectifier circuit, the controller circuit causes the regulator circuit to reduce or stop supplying current to the field coil. When an abnormal event occurs in the rectifier circuit, the circuit provided by the present invention can protect the rectifier circuit in real time.

Description

technical field [0001] The invention relates to a generator circuit, and in particular to a protection method for a synchronous rectification generator and a rectifier circuit. Background technique [0002] The conventional automotive alternator is composed of a rotor coil and a stator coil. When the excitation current passes through the rotor coil, the rotor coil can provide a magnetic field to the stator coil. When the internal combustion engine of the car drives the rotor coil to rotate, the rotor coil will generate a rotating magnetic field, making the stator coil generate AC power. The rectifier receives AC power from the alternator and rectifies it to produce DC power. This direct current energy can charge the battery. This battery can provide excitation current to the rotor coil. [0003] In general, a large amount of current flowing through a rectifier increases the temperature of the rectifier. When the operating temperature of the rectifier is too high, the re...
