Part Number: TIDM-1001
Other Parts Discussed in Thread: PMP41017

Hi Champ,

I am asking for my customer. They are studying two-phase interleaved LLC and referring to our TIDM-1001.

Asking for few questions about the design,

(1). What frequency is LLC_currentBalancing( ) function executing ?

(2). How to calculate LLC_iPri_PH1_Amps and LLC_iPri_PH2_Amps ?

(3). Is the current sharing implementation in TIDM-1001 is same as PMP41017 ?

Thanks and regards,

Johnny

Hi Johnny,

PMP41017 adopted the same aglorithum of current sharing with TIDM-01001. But, there is a mistake in the code, it should refer to the secondary current, other than primary current.

1, It is excuted same with control ISR, so it is 50kHz in default.

2, this is mistake in the code. primary current is only used for protection, and can't be correctly sensed;

3, it is same for now.
