Dear Forum

Hi

I design a LED Driver with TNYIII series , and i Windding a Transformer according of PI software Recommendation, What frequency I should to set in my Inductance Meter to Measurment Primary and Leakage Inductance?

Hi BR,

Standard manufacturing procedure for switch mode power supply transformer is 100kHz for measuring the inductance. 

 

For design verification you can set to 132kHz  or measure the actual inductance once it is operating trough oscilloscope waveforms.You can watch the procedure through this link:  Watch the 4th video.
