Hi friends ,
In PI EXPERT, transformer construction parameter Lp is mentioned as 520 micro henry
, at what test frequency on L.C.R. METER shall i check Lp , 100 Hz or 1khz?
L.C.R. Meter have only these two test frequencies for inductor measurement..
As s.m.p.s designed to operate at 132 khz.
Waiting for advice and explanation .
