摘要：

A test circuit for modular multilevel converter (MMC)-based voltage-sourced converter valves in high-voltage direct current (HVDC) system is dealt with. The proposed scheme has an ability to provide a submodule current having DC component as well as AC component to represent real operating condition of HVDC transmission system. There is no need of extra power supply to provide the DC current component because the scheme has inherent circulating DC current between rectifier and inverter valves. Therefore, only one small power rated DC power supply is necessary. Experiments are carried out to show the validity of the proposed test circuit.
