AI Technical Summary

Problems solved by technology

Other types of generators, such as permanent magnet and excitation hybrid generators, limit the scope of application due to their complex structure and high cost; although excitation generators have a simple structure and low cost, they are difficult to realize due to the unstable rotor speed when used in vehicles. The output voltage is stable, so that the use range is smaller and smaller

[0008] In the prior art, there are many kinds of voltage stabilization principles for vehicle excitation generators. There are mainly the following two types. One is to change the excitation current corresponding to the input of the rotor excitation winding as the rotation speed changes, so that the output The voltage is stable within a certain range, but the structure of the sampling circuit of this device is complex and expensive, and the cost of use and maintenance is high; the other is that the output current of the generator is rectified and stabilized by a rectifier regulator. It is difficult to achieve stable voltage, high energy utilization rate and simple and reliable circuit in a wide speed range
