Other Parts Discussed in Thread: UCC28951
Tool/software:
We are unable to check current sense current using KEYSIGHT InfiniVision MSOX3024T oscilloscope with High Voltage probe, Can you advise how to do that for UCC28951?. This test is for fine tuning Uniform Dead Time between all switches. Also we are using UCC28951 for designing PSFB Board for 4kW Charger. The dead time(DT) is Non-Uniform and there is a difference in Dead Time(DT1) and dead time (DT2) in all the high side switches A and C and low side switches B and D. The following results are the dead time between the switches
A and C VGS output DT1 500ns
A and C VGS output at DT2 1.7us
B and D VGS output at DT1 680ns,
B and D VGS output DT2 1.42us
Can you please advise how to change it as a Uniform Dead Time between all switches?. Thanks
