TIDA-010054: dual active bridge

Part Number: TIDA-010054

i am working on dab converter and want to know how to soft start the dab converter to avoid inrush

  • Hello, 

    There are a few things you need to consider to avoid big inrush current:

    1) increase the input voltage from 0 to 800V step by step or with a slow ramp

    2) increase the phase shift slowly, e.g. change it in steps of 0.002 pu as mentioned in the design guide(lab 2) 

    3) implement a current limit circuit(resistor parallel with switch) for soft start 

    Regards
