In the late 1880s, Thomas Edison and Nikola Tesla began a conflict known as the war of the currents. The two inventors and industrialists battled over whether Direct Current (DC) or Alternating Current (AC) should be used to distribute electricity. Ultimately, AC’s ability to work with transformers to easily increase and reduce voltage to transmit electricity across long distances won, and has reigned supreme for more than 100 years. Now though, the improvements in technology and growth in power electronics on the grid has brought DC back into the race. Here, I'd like to explain why.
