  • Publication number: 20190305560
    Abstract: A medium and high voltage energy conversion system is provided. An input terminal of each of high-voltage isolated DC/DC converters in a phase circuit of the system is connected to a common DC bus. Each of the high-voltage isolated DC/DC converters converts, based on an open-loop control strategy or a closed-loop control strategy, a DC input voltage of a cascade module connected to the high-voltage isolated DC/DC converter into an instruction value related to a voltage of the common DC bus. A system controller of the system calculates, based on at least a voltage-current double loop control strategy, a three-phase modulation instruction to be sent to the cascade modules in three phases according to a parameter related to the voltage of the common DC bus, to implement grid-connected control on three phase circuits.
