Researchers in the Department of Electrical Engineering (EE) at the Indian Institute of Science (IISc), Bengaluru and Delta Electronics India have developed a new fast charging solution for Electric Vehicles (EVs).
This novel cascaded H-bridge (CHB)-based multi-port DC converter directly connects to the medium-voltage AC (MVAC) electricity grid. Besides, it eliminates the need for large and expensive line frequency transformers (LFTs), which conventional charging stations rely on.
“These stations (conventional) also have multiple conversion stages involving stepping up or down current, or converting AC to DC, and vice versa. This can greatly increase cost and reduce efficiency,” according to IISc.
Tesla finally launches in Mumbai. But should you buy one?
The new converters can help address the growing power demands of fast charging EV stations, crucial for scaling up India’s EV infrastructure.
