Ano po ang eksaktong name nitong transformer na kulay yellow yung tape at yung core parang gawa sa bato sa halip na laminated steel core?

ETD Core malamang yan, "high frequency transformer" po

kadalasan hi frequency or chopper ang tawag ng mga tech...

but to be exact..

Ferrite core power transformers are widely used in switched mode power supplies (SMPSUs). The powder core enables high frequency operation, and hence much smaller size to power ratio than laminated iron transformers.

hindi ata toroidal, kasi di naman itsurang toroid (parang donut) yun..
ETD (shape) ferrite (material) core yung ginagamit..

ang toroid po eh yung inductor na ginagamit dun, yung mukhang polo candy na green may wire na nakaikot sa kanya.

ETD core ang tawag sa core nung xformer na yun. at high frequency transformer xa kasi high frequency pulses ang dumadaloy sa kanya.

Invite ko kayo sa post ko po ;D

bakit nga kaya "ETD" ang tawag dun sa shape ng core?  ???
di naman obvious yung "T" saka "D" sa shape nya..  ???

unlike sa "EE" core, makikita mo talaga na para syang dalawang "E"..

ETD is also an "E" core. yung center leg nya lang eh round.

wala pa rin sa shape nya yung "T" saka "D"..
pwede siguro "EO" core kasi round yung gitna.. hehe  ;D

fyi: meron din "EQ" core !  :o

ETD is E with round center legs (and compensated outer legs to match the round center ones)..most old PC PSU use EI (kung mapapansin niyo yung iba may sticker na EI-35, etc.)..35 denotes the size..
