RIR Power Electronics has successfully developed an advanced 25 kV–120 kA capacitor discharge semiconductor switch, representing a major step forward in India’s high-power electronics sector.
This achievement supports the “Make in India” initiative by delivering the country’s first locally developed high-voltage thyristor switch tailored for modern pulse power applications. It also boosts domestic manufacturing capabilities, lowers dependence on imports, and improves India’s position in the global power electronics industry.
At the core of the system is a 125 mm silicon-controlled rectifier (SCR) capable of blocking voltages up to 8 kV— developed in India for the first time. Multiple SCR units are integrated in a series configuration to achieve the required high-voltage performance, enabling precise control over extremely high current pulses.
The product has been rigorously tested and qualified at the high-voltage laboratory within RIR Power’s manufacturing facility in Halol, Gujarat, India, demonstrating robust performance and reliability under demanding conditions.
Designed for high-energy pulse power systems, the capacitor discharge switch can be deployed across a wide range of critical applications, including:
- Defense systems requiring controlled high-current pulses
- Advanced medical equipments
- Precision and selective directed energy technologies
With this development, RIR Power not only showcases technological innovation but also contributes to building a self-reliant, globally competitive electronics manufacturing ecosystem in India.
Dr. Harshad Mehta, Non-Executive Chairman, RIR Power Electronics, said: “We are proud to introduce the country’s first 25 kV switch, an achievement built on decades of expertise in high-power semiconductors and a sharp focus on technology and efficiency. This milestone underscores our commitment to ‘Make in India’ and ‘Atmanirbhar Bharat’, while enhancing the supply chain resilience and advancing India’s journey towards greater economic self-reliance.”
