Delta’s Dedicated R&D Fuels Growth in Power Electronics, Energy Systems, and E-Mobility

Delta Electronics India’s expansive R&D hub showcases homegrown engineering driving growth in power electronics, renewable energy, and electric mobility.

The media tour was led by Chief Technology Officer Shashidhar Mathapati, who guided media representatives through the 61,000 sq. metre, LEED Gold–certified campus, detailing how the facility has rapidly scaled its engineering strength. The centre currently houses 385+ R&D engineers, with plans to increase this to 750 over the next three years.

The visit opened inside the high-voltage labs, where 33 kV test systems, renewable inverters, and containerised data-centre solutions, all designed in India, undergo rigorous validation. Products are stress-tested in walking chambers simulating –40°C to 125°C, ensuring performance across extreme operating conditions. “Investing in advanced labs saves engineering hours and accelerates product development,” Mathapati said.

The tour then shifted to the automotive engineering division, backed by 100 specialists working on onboard chargers, DC-DC converters, and integrated powertrains. Thousands of automated test cases scrutinise lifecycle performance. “Automotive applications demand million-dollar precision. Our lifecycle management ensures 10-year customer support,” he added.

Delta’s market heft was unmistakable. The company commands over 63 percent share of India’s telecom-rectifier market and supplies UPS systems to global data-centre clients. The centre also develops a full stack of EV-charging solutions, from 700W portable chargers to battery-swapping stations for two- and three-wheelers.

Long-term investment continues to fuel this expansion. Of the USD 500 million pledged in 2015, 65 percent has already been deployed, with the remainder slated for completion by 2027. This pipeline is strengthening Delta’s smart-manufacturing and high-voltage product capabilities. “We’re among the few Indian players capable of designing and producing high-voltage systems at scale without relying on external platforms,” Mathapati noted.

With sustained engineering investment and a widening product portfolio, Delta is deepening its role in powering India’s renewable-energy and electric-mobility transition, building advanced solutions from India, for India and the world.
