Breakthrough In EV Charging: Compact, Transformer-Free Megawatt Converters Enable Ultra-Fast Charging

A groundbreaking EV charging technology uses compact, transformer-free megawatt-scale converters to deliver ultra-fast charging, reducing vehicle charge times from hours to just minutes.

Bengaluru: With EV adoption surging, fast charging stations now demand power levels exceeding one MW—comparable to supplying 1,000 homes. Conventional stations rely on bulky, copper- and iron-intensive line-frequency transformers (LFTs) and multiple AC–DC conversion stages, which drive up costs, material use, energy loss, and footprint.
