Ideal Power (IPWR) Conference presentation summary

Market trends and HVDC transmission advantages

• HVDC transmission offers lower electrical losses over long distances and resolves asynchronous grid connection issues compared to HVAC systems.

• The HVDC transmission market is projected to grow significantly, with Asia Pacific holding over 53% revenue share by 2025.

MMC submodule technologies and challenges

• Modular Multilevel Converter (MMC) designs use scalable submodules for high-quality output and reduced switching losses.

• Half-bridge submodules are low-cost and efficient but cannot block DC faults, while full-bridge submodules can block faults but are more expensive and have higher losses.

B-TRAN® innovation and performance

• B-TRAN® is a bi-directional BJT switch with low voltage drop, double-sided cooling, and cost competitiveness.

• B-TRAN®-based half-bridge MMC submodules can block DC fault currents due to the absence of internal anti-parallel diodes.

• Switching state analysis shows B-TRAN® submodules efficiently handle both positive and negative current cycles.
