The principle, structure and characteristics of the system were studied, three main functions for the system that inverter feedback function, rectifier traction capabilities and voltage ＆ unity power factor control functions were summarized. The running power factor, efficiency and protection compatibility of the system were simulated by simulation software provided infineon. The results show that there are significant advantages of bidirectional converter type system for absorption and utilization of regeneration energy, including bidirectional flow of energy, a control output feature, an adjustable power factor, high efficiency and ideal protection compatibility. Not only can it reuse train braking energy to achieve the purpose of energy conservation, but also improve the quality of power supply, and it is a more economical and effective solution of regeneration energy technology to urban rail transit.
