Abstract

With the development of science and technology and changes in demand, mobile energy storage pulse power research and application gradually rise. Due to the small size and high power requirements of the mobile energy storage power supply, the flywheel energy storage technology is gradually applied to the pulsed power supply. In this paper, pulse-CCPS system with a high-voltage generator-homopolar inductor alternator (HIA) is a flywheel energy storage device.The pulse power system has a high power, small size, can repeat the frequency of charging the excellent performance, can be well applied to the field of mobile work environment.

In this paper, the main part of the charging circuit of the capacitor charging pulse power system based on the induction generator is studied by means of simulation. The determination and design of the topology of the charging circuit are closely related to the performance of the charging power supply. Different topologies are used to influence the charging efficiency and design difficulty.

The second chapter analyzes the working principle and mathematical model of the induction generator. Because of the analysis of the motor flux linkage model in this chapter, it is found that the special cogging structure of the induction sub-motor makes the inductance matrix harmonic component negligible. Therefore, the model of the sensor generator with harmonic components is constructed. By discussing the induction generator The simplified equivalent model of the induction generator is obtained by using the condition of double reaction theory.

In the third chapter, the advantages and disadvantages of the topological structure charging performance of the main circuit of the main capacitor are compared with the requirements of the special requirements of the induction generator and the performance of the system by using the generator, the charging main circuit and the capacitor load combined simulation. Comprehensive analysis, and finally determine the three-phase semi-rectifier rectifier main circuit topology. At the same time, this chapter also studies the influence of the parameters of the charging circuit on the charging performance of the system.

In the fourth chapter, the transient process of the charging process with the rectified capacitive load of the induction generator is analyzed. By constructing the mathematical model, the commutation process is divided into three working modes, and then through the further analysis of the working mode , The effect of the commutation process on the charging performance of the power supply system is obtained, which provides theoretical support for the later charging performance and the integrated design of the generator and the charger.

In the fifth chapter, the parameters and models of the main switching devices are determined according to the design. Through the physical test of the small prototype system, the working performance of the power system under different conditions is simulated. Through the comparative analysis, it is found that the experimental results are not the same as those of the previous simulation results and the theoretical analysis, which indicates the correctness of the previous theoretical analysis and mathematical calculation.

Through the above contents, this paper completes the design and research of the main circuit in the high power recharging fast charging power source, builds the simulation model, and carries on the physical test verification.
