RIR Power Electronics Ltd has announced the successful development of a 25kV – 120 kiloampere (kA) capacitor discharge vertically integrated semiconductor switch, marking a significant milestone in India’s high-power electronics capabilities.
In a release, the company said that this innovation reinforces the government’s “Make in India” initiative by introducing India’s first indigenously developed 25kV 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 8kV 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 release said.
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; and precision and selective directed energy technologies.
Enhancing supply chain resilience
Dr. Harshad Mehta, Non-Executive Chairman, RIR Power Electronics Ltd, said, “We are proud to introduce the country’s first 25kV 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.”
