Abstract: Multi-terminal HV DC-DC converters are required to facilitate future HVDC infrastructure with the ability to interconnect and manage power flow between multiple HVDC networks. Existing topologies offer limited modularity
and scalability, making them difficult to implement in the fast-growing HVDC industry. In this disclosure, a multi-terminal modular multilevel converter (MT-MMC) is proposed as the first truly modular multi-terminal HV DC-DC
converter. The MT-MMC is made up of multiple subconverters that can be controlled individually with de-centralized controllers, allowing easy reconfiguration of the converter power circuit. The MT-MMC also realizes reductions in semiconductor effort and magnetic requirement when compared with conventional multi-terminal solutions. Case studies are conducted to demonstrate the versatility of the MT-MMC, and a comparative analysis is performed to highlight the advantages of the MT-MMC. Operation and performance of the MT-MMC are verified by simulation.T06-P01 University of Alberta | IP Management | 2018-12-20 | |

| Modular Multi-Level AC-AC ConverterInternational Patent Application # PCT/CA2022/051602, Edmonton AB
A modular multilevel AC-AC converter is provided which allows for the direct conversion of AC power between different voltage levels using half-bridge submodules. The converter has a partial power processing topology that exploits internal circulating DC currents to facilitate charge balance of submodule capacitors. This power transfer mechanism eliminates the centralized DC link required in conventional back-to-back modular multilevel converter (B2B-MMC) systems, thus enabling reductions in the semiconductor effort and submodule capacitor energy storage requirements typically required in a B2B-MMC solution. A modulation scheme is also provided for different AC voltage conversion ratios. The converter operation and controls are validated by simulation, and experimentation.T06-P01 University of Alberta | IP Management | 2023-05-04 | |
