사이리스터 시장 : 점유율 분석, 산업 동향 및 통계, 성장 예측(2026-2031년)

The Thyristor market size was valued at USD 1.77 billion in 2025 and is estimated to grow from USD 1.95 billion in 2026 to reach USD 2.31 billion by 2031, at a CAGR of 3.45% during the forecast period (2026-2031).

Demand is steady because utilities still favor line-commutated valves for multi-gigawatt high-voltage direct current (HVDC) corridors, even as silicon-carbide metal-oxide-semiconductor field-effect transistors (SiC MOSFETs) win share in automotive and high-frequency industrial drives. Procurement cycles are shaped by large grid projects that lock in orders years ahead, while module integrators diversify toward intelligent power modules that embed gate drivers and sensors. Price competition is intensifying in low-and mid-power ratings as Chinese discrete suppliers offer stud and capsule devices at 20-30% lower average selling prices than European peers. At the same time, counterfeit risk and certification delays are raising the importance of traceability and vertically integrated manufacturing.

Global Thyristor Market Trends and Insights

Expansion of HVDC Links Integrating Offshore Wind in Asia

Mega-scale offshore wind corridors continue to anchor new +-800 kV lines across China, South Korea, and Australia, each requiring between 200-300 press-pack devices per gigawatt of capacity. China's Hami-Chongqing and Ningxia-Hunan lines alone add 16 GW of converter capacity that specifies thyristor valves for line-commutated stages. Korea's West Coast Energy Expressway, approved in 2024, locks in 1,600 high-power devices through 2028 . Australia's Marinus Link adopts a mixed valve approach that still reserves discrete high-voltage positions for thyristors [hitachienergy.com]. Project backlogs therefore extend into the early 2030s, sustaining the Thyristor market even as voltage-source converter (VSC) choices rise.

Grid-Code-Mandated Dynamic Reactive-Power Compensation in EU Utilities

Updated ENTSO-E guidance now obliges distribution operators to maintain power factor within +-0.95 during peak and off-peak windows. Germany's Federal Network Agency sets a January 2026 deadline for plants above 10 MW to install dynamic support, stimulating orders for thyristor-switched capacitor banks and static var compensators. Spain has already deployed 1,800 MVAr of static synchronous compensators equipped with 48-pulse valve assemblies. Italy awarded 900 MVAr of flexible alternating current transmission systems (FACTS) gear in 2024 to reduce renewable curtailment. Compliance windows to 2028 underpin a rolling retrofit wave that supports the Thyristor market across Europe and North America.

SiC MOSFET Cannibalization in EV Inverters

Leading automakers have migrated to SiC devices that shrink inverter volume by nearly one-third and raise vehicle range by about 6%, displacing legacy thyristor-based auxiliaries in 400-V and 800-V systems. Mass-production scale has reduced the SiC premium to less than triple insulated-gate bipolar transistor (IGBT) pricing, encouraging mid-tier models to switch. Thyristor vendors lack comparable high-frequency switching capability, so content per vehicle fell below USD 6 in 2025 for many brands. Automotive revenue, formerly a growth pillar, is now retreating, limiting the Thyristor market's upside in mobility segments.

Other drivers and restraints analyzed in the detailed report include:

1. Modernization of Aluminum-Smelter Rectifiers in Gulf Cooperation Council Countries
2. Fast-Charging Infrastructure for Two-Wheeler EVs in China and India Using SCR Stacks
3. Counterfeit SCR Modules Causing OEM Recalls in Southeast Asia

Segment Analysis

Silicon-controlled rectifiers secured 65.71% of demand in 2025, anchoring low-frequency phase-controlled rectifiers across electro-chemical processing, motor soft-starters, and automotive alternator regulators. These devices combine 6,000-8,000 V blocking strength with surge tolerance above 10X rated current, while selling for under USD 15 in volume, which keeps the Thyristor market pervasive in price-sensitive industrial niches. Gate turn-off thyristors are forecast to log a 3.82% CAGR to 2031 as modular multilevel converters and urban rail upgrades adopt their self-commutating capability for simplified protection. The segment's growth is evident in China's high-speed train fleet, where new converters withstand vibration and temperature swings yet still rely on GTOs for fault isolation. Triacs, reverse-conducting, and asymmetric variants each address smaller pockets such as residential dimming or chopper drives, but none rival the scale of core SCR demand.

Design-in decisions reflect a trade-off between switching speed and per-ampere economics. The Thyristor market size for SCRs in industrial service remains stable, whereas GTO penetration rises where power density and ride-through dictate faster turn-off. Bidirectional triac sales stay flat because smart-home hubs replace legacy dimmers with solid-state relays. Reverse-conducting types gain in traction choppers, collapsing diode and thyristor into one die to cut inductance, while asymmetric parts meet HVDC poles that rarely see reverse stress. Suppliers that span all five device families capture cross-sell benefits, contributing to moderate revenue concentration.

Applications under 500 MW held 45.83% share in 2025, covering medium-voltage drives, regional static var compensators, and distribution-level converters. Standardized ratings streamline engineering, favorite for brownfield upgrades where footprint constraints override ultimate current density. Above 1,000 MW installations are forecast to grow at a 3.97% CAGR because multibillion-dollar HVDC corridors link offshore wind farms and cross-border grids. South Korea's 8 GW West Coast backbone will use about 1,600 stacked levels of high-power devices, each level series-connecting multiple press packs [home.kepco.co.kr]. Mid-tier 500-1,000 MW projects such as Saudi Arabia's 750 MW aluminum rectifier complex demonstrate balanced capital efficiency and manageable harmonics.

High-power orders favor capsule packages that tolerate 3-4 kW heat dissipation per device, necessitating direct liquid cooling. Certification under IEC 60747-9 can take 18 months, so incumbents with in-house test bays enjoy an access moat. Meanwhile, next-generation 8,500 V press-pack IGBT modules from Mitsubishi Electric offer smaller footprints, but their 40-50% cost premium limits adoption to space-constrained substations. The Thyristor market share in mega-watt segments therefore expands steadily as gigawatt-scale links multiply, even though wide-bandgap devices nibble at the mid-range.

The Thyristor Market Report is Segmented by Device Type (Silicon-Controlled Rectifier (SCR), and More), Power Rating (Below 500 MW, 500-1000 MW, and Above 1000 MW), Mounting and Package (Stud-Type, Capsule/Disc, and Module), Triggering Method (Electrical, Light, Pulse Transformer, and More), End-Use Industry (Industrial Drives and Motor Control, and More), and Geography.

Geography Analysis

Asia-Pacific dominated the Thyristor market with 45.48% share in 2025, lifted by China's addition of 12 GW HVDC capacity and India's electrification of 6,400 route-kilometers of railway track. Japan is reinforcing inter-island links with modular multilevel converter hybrids that still need high-voltage gate turn-off stacks, and South Korea's 8 GW backbone project sustains a multiyear order book. Australia's Marinus Link introduces VSC technology, trimming devices per megawatt yet extending construction through the early 2030s. The region also houses the world's largest discrete manufacturing clusters, with Chinese fabs shipping 420 million units in 2025 for drives, appliances, and traction.

The Middle East is projected to post the fastest 4.08% CAGR during 2026-2031 as Saudi Arabia's NEOM mega-project orders rectifiers for 4 GW of electrolyzers, each gigawatt requiring 800-1,000 high-current capsules [neom.com]. Solar plants such as Sudair and Al Dhafra integrate thyristor-switched capacitor banks and static var compensators that together exceed 900 MVAr of reactive support. Aluminum smelter upgrades in Bahrain and Qatar consume thousands of high-current devices, and at least three Gulf potline projects are queued through 2028. Regional demand therefore ties closely to energy-diversification budgets linked to hydrocarbon revenue.

North America and Europe exhibit moderate expansion. Germany's mandate for dynamic reactive support effective 2026 is triggering retrofits, and Spain's 1,800 MVAr STATCOM rollout showcases immediate grid benefits. Certification cycles for gate turn-off stacks in U.S. utilities, however, may exceed 18 months, delaying revenue recognition. South America centers on Brazil's 600 MVAr FACTS contracts that integrate Northeastern wind, while Africa's pipeline is led by South Africa's series capacitor corridor, yet fiscal constraints push commissioning beyond 2027. Collectively, the global footprint underscores how region-specific policies and project financing rates govern the Thyristor market trajectory.
