Simulation Design of Variable Frequency Speed Regulating System for Automobile Remanufactured Generator Test Bench Based on Matlab

摘要

There are many types of vehicle generators and their parameters are different. Therefore, the motor selected for the remanufacturing test bench should be suitable for most generators. Therefore, there is a certain requirement for the adjustment range of the motor speed. The AC-DC-AC frequency converter has a large frequency adjustment range, which can meet the motor speed control requirements. In this paper, the S imulink visual simulation tool Simulink modeling and simulation of AC-DC-AC inverter circuit, according to re-manufactured generator test to change the motor-related parameters, and the resulting waveform analysis.
