The rapid electrification of transport combined with an equally rapid build-out of high-power fast charging has thrust power electronics into the spotlight. While much attention goes to SiC MOSFETs and IGBTs for high-efficiency conversion, the humble silicon controlled rectifier (SCR) is seeing renewed demand as system designers rely on its robustness for protection, rectification and surge control in EV chargers and related grid assets.

Below we map the 2024–2025 market and technical picture: why SCRs matter, how fast chargers change technical requirements, and what manufacturers and system integrators should plan for in 2025.

EV and Charging Growth – the 2024-2025 Picture (facts & figures)

Global electric car sales topped 17 million in 2024, representing just over 20% of new-car sales; the global EV fleet and charger deployments surged in 2024 as well. Notably, more than 1.3 million public charging points were added in 2024, an increase of over 30% year-on-year lifting total global public charging stock substantially. These figures come from the IEA’s Global EV Outlook 2025.

India’s EV market has also accelerated: national stock and annual sales climbed sharply through 2024, with government programs (FAME/E-DRIVE and related initiatives) supporting public charging growth and electrified commercial mobility. Recent Indian analysis cites multi-fold growth in public charging availability and strong policy support for EV infrastructure in 2024-2025.

Why high-power fast charging increases SCR relevance

Fast DC charging (150 kW-350 kW and above) creates conditions that require robust rectification and protection:

• High inrush and surge currents during connection and fault events.
  
• Elevated thermal stress across the AC-DC front end and DC bus.
  
• Stringent safety and grid-stability requirements enforced by utilities.
  

While modern chargers increasingly use SiC and IGBT switching for conversion efficiency, SCRs continue to be widely used in:

• AC-DC front-end rectifiers (particularly for high-voltage, high-current rectification),
  
• Controlled soft-start/inrush-limiting circuits and
  
• Crowbar and fault-diversion protection where surge-handling and latching behavior are essential.
  

In short: fast chargers amplify the need for components that can absorb and safely divert large transient currents, an area where SCRs have proven strength.

Where the Silicon Controlled Rectifier (SCR) fits in modern EV charger design

SCRs and charger protection – why the silicon controlled rectifier still matters

Modern high-power chargers are hybrid systems: fast-switching SiC/IGBT stages paired with rugged SCR-based protection or high-power rectification. SCRs offer:

• Exceptional surge-current capability (important for crowbar/fault circuits).
  
• High-voltage blocking and thermal robustness for grid-connected front-ends.
  
• Simpler, lower-cost solutions for certain safety and fail-safe functions.
  

Technical literature on converter topologies and fast-charger design (2023–2024 reviews and conference papers) underline that hybrid architectures pairing high-efficiency switching with robust SCR protection achieve balanced cost, safety and reliability.

Market trends for SCRs – growth, segmentation and 2026 expectations

Market intelligence reports show the SCR market is not being eliminated by new semiconductors but evolving:

• IndustryARC projects the SCR market with a steady mid-single-digit CAGR (IndustryARC notes forecasted growth through 2030, reflecting demand across industrial, renewable and EV infrastructure applications).
  
• Broader power-controller analyses indicate multi-billion-dollar segments where high-power rectification and protection components are forecast to grow as EV chargers, renewables and industrial electrification expand.
  

Put plainly, system-level demand (chargers+grid interconnect+industrial electrification) creates continued volume opportunities for SCRs, particularly higher-rated devices and application-specific modules.

Practical implications for manufacturers and OEMs (2026 plans)

For companies designing or sourcing components in 2026, recommended actions include:

• Product re-engineering: develop SCRs with improved dv/dt immunity, lower gate drive thresholds, and thermally-optimized packages to suit charger front-ends.
  
• Hybrid system focus: position SCRs as complementary parts in SiC/IGBT-dominant converters use them for protection, soft-start and grid-interface rectification.
  
• Standards & compliance alignment: ensure SCR modules meet grid-code and EV-charger safety standards that utilities and highway operators increasingly demand (especially for >150 kW charging stations).
  
• Localized supply chains: with charging deployments accelerating globally in 2024-25 (and India pushing public charger expansion), consider regional manufacturing or stocking strategies to reduce lead times and meet EPC project schedules.
  

(For companies like  Glomore Electrotech, these strategies map directly to product roadmaps: ruggedized SCR modules, charger-ready assemblies and partner ecosystems for EPCs and charger OEMs.)

Conclusion

The rapid expansion of electric vehicles and fast-charging infrastructure is redefining not replacing the role of the silicon controlled rectifier in modern power electronics. As charging power levels rise and grid integration becomes more complex, SCRs remain essential for robust rectification, surge handling and fault protection.

Moving into 2025, the demand for reliable, high-power, and grid-compliant EV charging systems will continue to support SCR adoption, particularly within hybrid power architectures. In an increasingly electrified mobility ecosystem, SCRs will remain a critical enabler of safe, stable and scalable charging infrastructure.

Key Takeaways

• Global EV sales reached 17 million cars in 2024; over 1.3M public chargers were added in 2024, a major driver for power-component demand.
  
• Fast charging increases stress on front-end rectification and protection areas where SCRs provide clear technical advantages.
  
• Market forecasts indicate steady SCR market growth through the decade, buoyed by EV infrastructure, renewables and industrial electrification.
  
• For 2025, manufacturers should prioritize hybrid-system compatibility, improved SCR specs (dv/dt, thermal) and supply-chain agility particularly in fast-growing regions like India.
