  Press Releases

  • RIYE Electric Co., Ltd., a global leader in power quality and voltage regulation solutions, is proud to announce its participation in the upcoming SEMICON Taiwan, the premier event for the global semiconductor manufacturing supply chain. Addressing the industry’s critical demand for high-precision power, RIYE Electric will showcase its "Five Pillars of Power Protection": Transformers, Automatic Voltage Regulators (AVR), Uninterruptible Power Supplies (UPS), Dynamic Voltage Restorers (DVR), and Harmonic Filters.

    Global Compliance: UL & CE Certified Solutions for Every Series

    As semiconductor equipment manufacturers expand globally, regulatory compliance is no longer optional—it is a necessity. RIYE Electric’s comprehensive lineup of Transformers (including dry-type, cast resin, and oil-immersed models) and AVRs are designed to meet the world’s most stringent standards.

    • The RIYE Advantage: Every product series in RIYE’s transformer and regulator portfolio is fully UL and CE certified. This ensures that equipment integrated with RIYE solutions can seamlessly enter the U.S., European, and Asian markets without the delays and costs associated with secondary certifications.

    DVR & UPS: Guarding Against Wafer Scrap and Downtime

    In a semiconductor Fab, a voltage sag lasting only milliseconds can lead to catastrophic equipment halts and millions of dollars in scrapped wafers. RIYE Electric’s Dynamic Voltage Restorer (DVR) is engineered specifically to mitigate these risks.

    • Performance: With microsecond-level detection and a response time of less than 2ms, RIYE’s DVR provides instantaneous compensation for voltage sags.

    • Reliability: When paired with RIYE’s industrial-grade UPS systems, the solution creates a "Power Firewall," ensuring 24/7 continuous operation for critical lithography, etching, and chemical vapor deposition (CVD) processes.

    Harmonic Mitigation: Purity for Precision Tools

    The increasing complexity of non-linear loads in modern Fabs introduces harmonic distortion, which can overheat equipment and interfere with sensitive sensors. RIYE’s Harmonic Mitigation solutions effectively filter electrical noise, delivering pure sine-wave power to ensure the stability of Automated Material Handling Systems (AMHS/OHT) and high-resolution metrology tools.

    A Mission for Stability

    "The semiconductor industry has a near-zero tolerance for power fluctuations," said a representative for RIYE Electric. "Our mission at SEMICON Taiwan is to demonstrate how RIYE’s certified power solutions—ranging from campus-wide distribution to tool-level regulation—serve as the silent guardians of the production line. We don't just provide hardware; we provide the peace of mind that enables our customers to focus on innovation and yield."

      • Precision Filtering: Achieves over 95% harmonic removal (THDi), making it ideal for production lines with fluctuating loads, such as OHT systems and back-end testing tools.

      • Modular Scalability: The compact, modular design allows facility managers to expand capacity as power demands grow.

    • Passive Harmonic Filters (PHF): Economical, Robust, and Reliable

      • Targeted Suppression: Engineered to intercept specific characteristic harmonics (e.g., 5th, 7th, 11th orders).

      • Industrial Durability: With no electronic switching components, PHF offers extreme reliability for heavy-duty facility infrastructure, including HVAC and large-scale water pumps.

      • Energy Efficiency: Reduces line losses and improves power factor, assisting Fabs in achieving their ESG and carbon reduction goals.
