RIR Power Electronics Limited operates as a global provider of high-power semiconductor solutions, focusing on energy efficiency and innovation. The company's portfolio includes semiconductor devices, assemblies, and energy management systems designed for modern energy applications.

RIR Power Electronics Limited has secured its first international order for 120 units of its 125mm 5kV silicon-controlled rectifier (SCR) thyristors, marking a significant expansion in its global footprint. The order, received from a Class I Electrical EPC contractor, underscores the growing demand for the company's high-power semiconductor solutions in heavy-power applications. Execution of this order is scheduled for completion by the end of 2026.

The 125mm 5kV SCR thyristors utilize a press-pack construction designed to handle very high peak currents and high di/dt pulses. These devices are engineered for high mechanical reliability and optimized lifetime control, making them suitable for critical infrastructure projects. The company positions these products as ideal for applications requiring high current handling and robustness.

Product Applications

RIR Power Electronics' high-power press-pack thyristors are deployed across various sectors due to their low thermal resistance and excellent surge current capability. Key application areas include:

• HVDC transmission valves
• Static VAR Compensators (SVC)
• Medium-voltage soft starters
• High-power rectifiers
• Crowbar protection systems
• Traction & legacy locomotive systems
• Defense systems

Strategic Expansion

Management highlighted that this order win is one of the largest single orders for the company's range of 125mm pulse power thyristors. Mr. N. Ramesh Kumar, MD & CEO of RIR Power Electronics Limited, expressed optimism about expanding the mandate with Class I Electrical EPC Contractors in the future.

The company is also advancing its domestic manufacturing capabilities by setting up a state-of-the-art Silicon Carbide (SiC) semiconductor manufacturing plant in Odisha. This initiative aims to strengthen India's semiconductor industry and establish the country as a global hub for power semiconductors.
