With the surging popularity for electric vehicles (EVs), rapid charging is a challenge as it requires power delivery exceeding 1 MW (which can power about 1,000 homes). Conventional charging stations rely on bulky line frequency transformers (LFTs), which are expensive due to extensive use of copper and iron. These stations 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.
