DC transformer based hybrid AC/DC microgrid and DC distribution network

The isolated bidirectional DC/DC converter has many advantageous characters such as high efficiency, high power density and good stability. It can be used to connect AC bus and DC bus by cooperating with bidirectional interlinking converter (BIC). It can also eliminate the gap between DC buses from...
