The function of the regulator is to protect the battery, is the battery's charging protection device, so as not to overcharge and affect the life. The principle is this, the regulator has a detection circuit inside, when the battery voltage is higher than the set value (generally 14v or 28v), the switch tube will be disconnected, stop power supply to the generator excitation coil, the generator does not have excitation current can only empty (stop power generation). When the voltage is below 12v, the switch tube is switched on and the generator receives the excitation current before generating electricity. When the engine speed changes, the regulator can automatically change the current of the excitation coil, making the output of the engine relatively stable.
