摘要

A three-phase connection converter (102), comprising:a DC sub-grid connection port (201, 202), an AC sub-grid connection port (212, 213, 214), a voltage source converter (205), a current sensing circuit (209, 210, 211), a voltage sensing circuit (203), a controller unit (207), a gate driver circuit (206), and a filter unit (204, 208);a DC sub-grid connection port configured to be coupled to a DC sub-grid (101) receiving or transmitting DC power;an AC sub-grid connection port configured to be coupled to an AC sub-grid (103) receiving or transmitting AC power;a controller unit configured to continuously receive the measured electrical parameters from the voltage and current sensing circuits and calculate an operating condition based on determining the operating condition to send pulses to the voltage source converter through gate driver circuits;a gate driver circuit configured to receive the pulses from the controller circuit and convert them into a form that drives the voltage source converter switches;a filter circuit configured to smooth the electrical voltage and current flowing through the connection converter.
