This paper proposes a transformerless power router used in high-speed electric railway. Its primary circuit is based on a four-leg high-voltage converter which provides multiple power flow paths. Its voltage equations are established with a relocated neutral point. And a matching control strategy is presented which is helpful to lower the converter scale. This power router is capable of reducing the negative sequence currents injected into utility power system as well as providing uninterruptible power supply to the neutral section. Simulation results validates both the circuit topology and the control strategy.
