The dual active full bridge (DAB) converter is a high-performance DC-DC topology characterized by zero-voltage switching (ZVS) of all switches, low electromagnetic interference (EMI), and high efficiency. It employs two active full bridges connected through a high-frequency transformer. The dual-bridge configuration allows for bidirectional power flow, making the DAB converter suitable for applications such as uninterruptible power supplies (UPS) and renewable energy systems. Its power equation, P = 2V_inV_out/(V_in + V_out), illustrates the relationship between the input and output voltages and the power transfer capability of the converter.
