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 | | Multiport Converter with Independent Control of AC and DC Power Flows for Bipolar DC DistributionT06-P01 University of Alberta | Publication | 2020-08-12 | | The Modular Multilevel DC Converter with Inherent Minimization of Arm Current StressesT06-P01 University of Alberta | Publication | 2020-05-06 | | DC/AC Voltage Sourced Converter with Auxiliary DC Port for Renewable Energy ApplicationsT06-P01 University of Alberta | Publication | 2020-10-30 | | Decoupled Floating Capacitor Voltage Control of a Dual Inverter Drive for an Open-Ended Winding Induction MotorT06-P01 University of Alberta | Publication | 2019-12-06 | | Prize Paper awardT06-P01 University of Alberta | Award | 2019-06-19 | | APIC 2021 Annual ForumT06-P02 University of Alberta | Activity | 2021-06-28 | | CIGRE Canada Conference & Expo T06-P02 University of Alberta | Activity | 2022-10-31 | | APIC 2022 Annual ForumT06-P02 University of Alberta | Activity | 2022-05-09 | | Best Student Paper Award Best Student Paper Award at the CIGRE Canada Conference held in Calgary, for presentation "Hybrid LCC-VSC Bipolar HVDC Systems for DC Power Tapping Studies"T06-P02 University of Alberta | Award | 2022-11-03 | | 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 | | Hybrid LCC-VSC Bipolar HVDC System for DC Power Tapping StudiesBest Student Paper Award at the 2022 CIGRE Canada ConferenceT06-P01 University of Alberta | Award | 2022-05-10 | |
