Development of UHV Converter Valve Control Equipment Based on Domestic Chip
Year: 2026
Type: conference-paper
Abstract: To overcome the critical bottleneck of reliance on imported chips for UHV(Ultra-High Voltage) converter valve control equipment and address domestic chip challenges in UHV applications — including high power consumption, inconsistent parameters, and insufficient engineering validation — this study focuses on developing fully domestically produced valve control systems. Guided by the principles of “reliability-first, performance alignment, and engineering maturity,” the project achieves 100% localization of core components including Fudan Microelectronics' FMQL45T900 SOC, Unisoc's FPGA, and GigaDevice's memory chips. Targeted optimizations were implemented for chip-level thermal management, signal quality enhancement, and system isolation redundancy. Through rigorous reliability testing, third-party EMC validation, and RTDS closed-loop simulation, the UHV valve control system has successfully transitioned from “import dependency” to “domestic autonomy,” providing critical infrastructure support for national energy security.
