half bridge converter

Hello Nash,

You can check our Continuous Mode PFC & LLC Controller with Integrated Half Bridge Drivers, see http://www.powerint.com/en/products/hiper-family/hiperplc

hello,

sorry to keep bothering...but when do you think the application note will be ready on this chip ?

If you buy new RDK-189, you will find full information attached with. :)

Best Regards

thankyou for that.......actually before i buy rdk189 i would like to see an app note telling of the transfer functions so i can do isolated feedback control..................if there is no transfer function equation (with s operator) then i am not good enough to be able to derive it myslef....though i suppose i could buy a gain/phase analyzer and do by trial and error....but i would like to see bode plots also.

Hello Crusher,
Please have a look for Figure 8 on your RDR-189.
Main transformer has wrog pin numeration on secondary side.
On the bottom, insteed of 12 should be 13
and insted of 11,12 (doubled) should be 9,10 pin.
In one of the secondary windings is 0,001mm wire, but it should be 0,1 mm
By the way, as we can see, the PCB is ready for two different coilformers.
One of them is TDK transformer, but which is alternative coilformer ?
Is 100uH primary leakage inductance correct value ?
If primary inductance is 330 uH tken lekage will be over 30%
Is it specialy for this LLC application ?
Best Regards
