Each of which has two phases in the primary winding. Don't know what this means. It's a single-phase transformer. The primary may be connected phase-phase, but what's the purpose of the center tap? when I disconnect one of phases (for example L1) from Tr2, there is still voltage in that disconnected phase that is due to re
sure, use a transformer with the output center tapped. connect 40V to center tap, and put 5V square wave on primary
The following simple balanced modulator may help you to understand. We have a 10MHz carrier input on N1 of the transformer. We apply a modulation signal at the center-tap on the primary. In the first plot, we have a10kHz pure sine-wave modulation with the balancing pot P1 just of the 50% mark. You can see the carrier, and the two (...)
Hi guys A newbie question 96354 need to wire this transformer, both primaries and both secondaries respectfully have the same number of windings, can I wind them bifiliar (simultaneously) or single wire with a center tap. Thank you in advance for your quick reply - :-D Theunis
i want to make an inverter ckt of i/p vg 12v dc and o/p vg 240v ac , i need 2 - 3A current at o/p side. and i wants to do it without center tap transformer and i can use 12v to 240v stepup transformer.
hai, i want to test 0v-115v-230v to 15v-0v-15v center tape transformer.actually i need 15v ac for power supply input.but i have 230v ac source only available.how i get 15v ac use of 230v ac input.pls help me.
I have a system which inputs sine wave to the primary side of a transformer and the same system takes output at the secondary (center tapped output) Now if my system ground is shorted at primary and the same system ground is shorted to the output at the secondary, then that means I have put a path between (...)
hi all, i want to design balun in ASITIC for RFIC i m getting balun structure i.e. primary & secondary turns i dont know how to center tap the secondary winding how to do the analysis whether 2 port or 3 port how to find the coupling coefficients between pri & sec What equivalent balun model to use in cadence for Schematic (...)
u can use the center tapped tranformer and ignore the other primary winding what exactly u want to do with it ? khouly
hello everyone: There are only function generator and digital CRO for tseting the transformer. I have problems on ways of connections and input signal for testing on center- tap one. Pl give some suggestions to me... Best regards
Hello I'm trying to figure out how to drive VFD (not variable freq drive but vaccum flourescent display) and it calls for 2.5 AC fillament drive but all example schematics show a transformer with a center tap. My questions are - how does one get that transformer and what about the primary coil? How can I use a center (...)
