The eventual goal of high-voltage direct-voltage (HVDC) systems is to implement HVDC grids. The modular multilevel converter (MMC) has been identified as the best candidate for the realization of an HVDC grid by eliminating the shortcomings of conventional voltage source converter (VSC) technology. The related research has focused on efficient control schemes. new MMC topologies. https://www.markbroyard.com/great-pick-tablecraft-invertatop-squeeze-bottle-24-oz-translucent-12-pack-cheap-limited-save/
