Dual Active Bridge Converter (DAB)
Description
This converter has bridges on the primary and secondary sides of the transformer. It performs bi-directional power conversion by controlling the phase between the reference phase (primary side bridge) and the control phase (secondary side bridge). ZVS is possible, and it is popular for power supply of high-voltage, high-power storage systems such as EV and power conditioners.
Overview
- Support Bi-directional operation
- SiC MOSFET contribute high efficiency
- Output voltage may be changed depending on battery voltage
- By stacking DAB circuits, it is possible to support more higher voltage
