HELLO,TI teams:
For the previous discussion of cold start posts in Jan 27, 2018(reply time), I think low side inductor current decrease condition is (N*Vout – Vin)>0 when bidirectional converter works。
When Vout<Vin/N ，need an additional boost converter for start-up。
But in practical application，400V Bus Often there are high capacity capacitance，for example，8000uF。 Boost converter need a few seconds for start up，and longer time for Vin=60V。
What‘s worse，when Bus voltage up to 150V，Some equipment on Bus start to work and pull down Bus voltage。
Need solutions.
