Mumbai: RIR Power Electronics Limited has announced the successful development of a cutting-edge 25 kilovolt (kV) – 120 kiloampere (kA) Capacitor discharge vertically integrated semiconductor switch, marking a significant milestone in India’s high-power electronics capabilities.
This innovation reinforces the government’s Make in India initiative by introducing India’s first indigenously developed 25 kV high-voltage thyristor switch designed specifically for advanced pulse power applications. The breakthrough strengthens domestic manufacturing expertise, reduces reliance on imports, and enhances India’s competitiveness in the global power electronics market.
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:
- Defence systems requiring controlled high-current pulses
- Advanced medical equipment
- 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 Ltd, 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 ‘Aatmanirbhar Bharat’, while enhancing the supply chain resilience and advancing India’s journey towards greater economic self-reliance.”
