This project deals with a triple active bridge converter capable of achieving ZVS across the full load range with wide input voltage while minimizing heavy load conduction losses. This topology comprises three full bridges coupled by a three-winding transformer. By adding a third full bridge to the traditional DAB, ZVS operation is maintained at light load without penalty on conduction loss at heavy load, while maintaining the same total semiconductor area. The input DC voltage supplied to the triple active bridge DC to DC converter with different transformer ratio is used to obtain high and low voltage as output. By using triple active bridge , multi range of output can be obtained and multiple loads can be connected . Multi range of output in the sense the transformer used in this topology consist of one primary winding and many secondary can be connected to get the desired output.
