AC/DC hybrid distribution network can realize the high penetration utilization of renewable energy and modular multilevel converter (MMC) is the key equipment to connect AC grid and DC grid. In this paper. the direct modulation based on the virtual resistor and the reference value of dc-bus voltage is adopted. and instantaneous-value model of three-phase half-bridge MMC is derived by ... https://www.chiggate.com/earthbath-facial-wipes-25ct-fashion/
