What to set switching frequency to in overloaded LLC converter?
« on: June 20, 2022, 05:14:46 pm »
Hi,
Do you agree that bottom of page 11 of the following App Note is nonsense?

LLC converter design guide with ICE2HS01G:
https://www.infineon.com/dgdl/Design+Guide+for+LLC+Converter+with+ICE2HS01G+05072011.pdf?fileId=db3a304330f68606013103ebd94f3e98

It says: “During over-current, the load impedence is considered to be shorted”……..how so?.... when its shorted, the load impedance is zero??
They are trying to find what to set the switching frequency to during overcurrent.
