Other Parts Discussed in Thread: TINA-TI, TPS55340
The boost converter TPS55340QRTERQ1 is used in the design to charge the bulk capacitor to 32V by supplying 9-19V input. When simulated in TINA-TI, we are observing that the inductor current is beginning to oscillate after remaining in the current limit for 43ms. The oscillations begins at 298ms(refer the simulation result). Please help us with the reason for the occurrence of the oscillations.

1) inductor current (IL1)
2)Voltage measured at the bulk cap (VCAP)
