The invention relates to the track traffic traction power supply technology field, and especially provides a track traffic regenerative braking energy feedback bidirectional conversion circuit based on IGBT. The circuit is composed of a power grid DC, a direct current isolation switch DC-QS, bidirectional alternating current convertor units AC/DC, a capacitor C1, a reactor L1, an alternating current breaker AC-QF, an isolation transformer F, an alternating current isolation switch AC-QS and a traction transformer station power grid AC in series connection from left to right in order. Eight bidirectional alternating current convertor units AC/DC are in parallel connection. In the same device, the provided bidirectional conversion circuit can be used for inversion of DC/AC and also can be used for rectification of DC/AC. Without addition of device hardware configuration, the device duty ratio is raised greatly, and the duty ratio can reach more than 95%.
