Other Parts Discussed in Thread: UCC28950
Hi,
What is the best and safest to power up a high voltage (800V) phase shifted full bridge converter for the first time to ensure safe operation without damaging any components.
Is it a good idea to start testing the board from 50V and increase the voltage slowly while monitoring the dead time and Vds of the bridge MOSFETs?
I have observed that everytime I try to run the converter at low input voltage i.e., 100V, the secondary side synchronous MOSFETs fail short circuit.
Thanks
