Development of Rail Transit Bidirectional Multilevel Converter Measurement and Control System

摘要

For rail traffic bidirectional multi-level PWM converter, designed a new type of measurement and control system. The paper details the system hardware circuit and software implementation. The experimental results of field experiments show that the system has realized the rapid operation of bidirectional multi-level converter and made the operation of urban rail transit train better control performance, reliability and traction performance, and has better popularization value of engineering application.
