| 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.

| Multi-terminal modular DC-DC converter for DC networks (CAN)Canada Patent Application No.: CA 3,028,231
Filed on: 2018-12-20
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. University of Alberta | IP Management | 2018-12-20 | Kish, G., Sunny Kung |

In this patent document, the partial energy processing (PEP) concept is developed to achieve a high-efficiency and full MPPT range PV MIC. For PEP the energy is flown from the source to the load through multiple paths. The total energy then is divided into arbitrary portions in power-time plane and each portion is transferred through a different path to achieve the best conversion performance. A three path PEP structure that is specifically suitable for PV MIC application is proposed and realized in component level. A 220 W prototype converter is implemented to justify the converter principal of operation and analyses. Using the proposed PV MIC, MPPT is achieved for the full range of the PV power generation while 99.6% to 96.5% efficiency is achieved for the power mismatches in the PV module ranging from 0 to 50% of the maximum module power generation capability, respectively. The efficiency drop is shown to be linear with power mismatch level without any abrupt reductions that is commonly observed in conventional PV module integrated converters.

Abstract: A power generation device. The power generation device includes a piezoelectric cantilever beam positioned proximal to an alternating magnetic field; a magnetic mass attached to the piezoelectric cantilever beam, where the magnetic mass may be positioned within a portion of the alternating magnetic field; and a vacuum enclosure encapsulating the piezoelectric cantilever beam and the magnetic mass to vacuum seal the piezoelectric cantilever beam and the magnetic mass within the vacuum enclosure. The piezoelectric cantilever beam may be configured to have an output resistance based on a vacuum level of the vacuum enclosure.
