Fusion Power System addresses the most demanding power conversion challenge in human engineering — supplying hundreds of kiloamperes at tens of kilovolts with sub-0.1% regulation accuracy and millisecond-level response. NexPower's SCR-based solution for Poloidal Field (PF) and Central Solenoid (CS) coil power supplies leverages 12-pulse thyristor rectifier topology with anti-parallel bridge configuration.

STATCOM (Static Synchronous Compensator) is a next-generation dynamic reactive power compensation device based on Voltage Source Converter (VSC) technology. It provides fast, continuous reactive power regulation with response time under 5 milliseconds — far outperforming traditional SVC. A key advantage: output current remains at full capacity even when system voltage dips, making it uniquely effective during grid disturbances.

APF (Active Power Filter) is a power electronic device designed for dynamic harmonic suppression and reactive power compensation. It detects harmonic components in load current and injects equal-amplitude opposite-phase compensation currents to achieve active harmonic elimination across the full 2nd~50th range with over 97% filtration rate. Unlike passive filters, APF introduces no resonance risk and operates safely in parallel with existing systems.

SST (Solid State Transformer, or Power Electronic Transformer PET) is a next-generation power conversion device that replaces traditional iron-core transformers with high-frequency power electronics. It delivers AC/DC transformation in a single compact unit with end-to-end efficiency above 98.5%, footprint reduced to 1/3~1/5 of conventional transformers, and millisecond-level bidirectional power flow control.

Flexible AC Transmission Systems (FACTS) is a market worth annually about 1.3 BUSD and we estimate that the power semiconductor market for this segment is around 80 MUSD. The main applications of interest for us are Static VAr compensators (SVC) using thyristors and STATCOM using IGBT and IGCT. Among the main manufacturers we find well-known names as Hitachi Energy, Siemens, GE and RXPE.
