Delta’s Strengthened R&D Backbone Accelerates Innovation in Power Electronics, Energy Systems & E-Mobility

Delta Electronics India is leveraging its advanced LEED Gold–certified R&D centre to accelerate innovations in high-voltage solutions, automotive technologies, and EV charging systems—supported by expanding engineering talent and sustained long-term investments across power electronics, renewable energy, and electric mobility.

Delta Electronics India showcased the breadth of its in-house engineering capabilities during a media tour of its 61,000 sq. metre R&D campus. The facility has become a key driver of the company’s growth across power electronics, energy systems, and e-mobility.

Chief Technology Officer Shashidhar Mathapati led the tour, explaining how the centre has rapidly expanded its research strength. The hub currently employs 385+ R&D engineers, with plans to scale up to 750 engineers within the next three years.

The visit began inside the high-voltage laboratories, where India-designed 33 kV test systems, renewable-energy inverters, and containerised data-centre solutions undergo intensive validation. Equipment is tested in walking chambers that recreate extreme climates—from –40°C to 125°C—to verify reliability under diverse conditions.

“Advanced laboratory infrastructure cuts engineering time and speeds up product development cycles,” Mathapati noted.

The automotive R&D division was another major highlight. With a team of 100 specialists, this unit develops onboard chargers, DC–DC converters, and integrated powertrain systems. Thousands of automated test cases are executed to assess lifecycle durability.

“Automotive engineering demands extremely high precision. Our lifecycle approach ensures 10 years of customer support,” he added.

Delta’s strong market presence was evident throughout the visit. The company retains over 63% share in India’s telecom-rectifier market and supplies UPS systems to major global data-centre operators. The R&D centre also builds an extensive range of EV-charging solutions—from compact 700W portable chargers to battery-swapping platforms for two- and three-wheelers.

Long-term capital investment continues to reinforce Delta’s capabilities. Of the USD 500 million committed in 2015, 65% has already been deployed, with the remaining investment planned by 2027. This capital is expanding Delta’s smart-manufacturing infrastructure and strengthening its high-voltage product portfolio.

“We’re among the very few Indian manufacturers capable of designing and producing high-voltage systems at scale, entirely on our own platforms,” Mathapati stated.

Backed by sustained R&D expansion and a rapidly widening portfolio, Delta is solidifying its position as a key enabler in India’s renewable-energy and electric-mobility transition—developing advanced, future-ready technologies from India, for India and global markets.
