RIR Power Electronics Limited has achieved a significant technological breakthrough by successfully developing India's first 25 kV-120 kA high-voltage thyristor switch. This milestone represents a major advancement in the country's power electronics manufacturing sector and demonstrates the company's commitment to indigenous innovation under the Make in India initiative.

Technical Innovation and Specifications

The cutting-edge capacitor discharge vertically integrated semiconductor switch marks a crucial step forward in India's power electronics capabilities. 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.

Parameter: Details
Voltage Rating: 25 kV
Current Capacity: 120 kA
Core Technology: 125 mm Silicon-Controlled Rectifier
Blocking Voltage: Up to 8 kV per SCR unit
Configuration: Multiple SCR units in series
Testing Location: High-voltage laboratory, Halol, Gujarat

Applications and Market Impact

The product has been rigorously tested and qualified at the high-voltage laboratory within RIR Power's manufacturing facility in Halol, Gujarat. Designed for high-energy pulse power systems, the capacitor discharge switch can be deployed across critical applications including defense systems requiring controlled high-current pulses, advanced medical equipment, and precision directed energy technologies.

Make In India Alignment

The development directly supports the government's Make in India and Atmanirbhar Bharat initiatives, contributing to the nation's self-reliance goals in critical power infrastructure components. This innovation reduces dependence on imported high-voltage switching solutions and strengthens domestic manufacturing capabilities in the power electronics sector.

Leadership Perspective

Dr. Harshad Mehta, Non-Executive Chairman of RIR Power Electronics Ltd, emphasized the significance of this achievement: "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."

This technological achievement positions RIR Power Electronics at the forefront of domestic high-voltage switching technology development and represents a significant step toward establishing India as a capable manufacturer of sophisticated power electronics components.

What is RIR Power Electronics' production timeline and capacity plans for scaling up manufacturing of these 25 kV thyristor switches?

How might this breakthrough impact India's competitive position in global defense and medical equipment export markets?

Which major Indian defense contractors or medical device manufacturers are likely to be early adopters of this indigenous technology?

RIR Power Electronics Limited has announced the grant of 7,50,000 employee stock options under its newly established ESOP 2025 scheme. The company's Nomination and Remuneration Committee approved this grant during its meeting held on February 13, 2026, as part of the "RIR Power Electronics Limited Employees Stock Ownership Plan – 2025."

ESOP Grant Details

The granted stock options are designed to provide eligible employees with ownership participation in the company's growth. Each option can be converted into one equity share of the company with a face value of ₹2 per share.

Parameter: Details
Total Options Granted: 7,50,000
Exercise Price: ₹100 per option
Face Value per Share: ₹2
Convertible Shares: 7,50,000 equity shares
Approval Date: February 13, 2026

Vesting Schedule and Terms

The ESOP 2025 scheme features a structured vesting schedule spread over 36 months to ensure employee retention and long-term commitment. The vesting follows a graduated approach with different percentages allocated across three distinct periods.

Vesting Period: Percentage Monthly Options Timeline
Year 1: 33% - 12 months from grant date
Year 2: 2.75% monthly 20,625 options Months 13-24
Year 3: 2.833% monthly 21,250 options Months 25-36

Exercise and Compliance Framework

Once the options vest, eligible employees have a four-year window to exercise their vested options from the date of completion of vesting. The scheme operates under the oversight of the Nomination and Remuneration Committee, which serves as the designated Compensation Committee for the ESOP 2025 plan.

The company confirmed that the scheme complies with the Securities and Exchange Board of India (Share Based Employee Benefits and Sweat Equity) Regulations, 2021. The grant is based on eligibility criteria specified within the scheme framework, ensuring fair distribution among qualified employees.

Current Status

As this represents the initial grant under the ESOP 2025 scheme, several parameters remain not applicable at this stage, including options exercised, money realized from exercises, shares arising from option exercises, lapsed options, and any variations in terms. The company will provide updates on these metrics as the scheme progresses through its vesting and exercise phases.

The implementation of this employee stock option scheme demonstrates the company's commitment to aligning employee interests with shareholder value creation and fostering long-term employee engagement in the organization's growth trajectory.
