Transformer efficiency is a measure of how effectively a transformer converts electrical energy from its primary winding to its secondary winding. It is the ratio of the output power delivered by the transformer to the input power supplied to it, expressed as a percentage. A higher efficiency ind...
The turn ratio of the RF transformer is calculated by using the following formula. Where, Np/Ns= Turn ratio Np= Number of turns in the primary coil Ns= Number of turns in Secondary coil Zp= Input/Primary impedance Zs= Output/Secondary impedance ...
the turns ratio of the transformer is measured, and the turns ratio measurement error value theta of the test of not connecting the neutral points is obtained; the value theta is substituted into the following reduction formula to obtain the actual turns ratio error epsilon of the transformer. ...
As an example, anoutput transformerwith a primary to secondary turns ratio of 31.6:1 would allow the output valves to see the 8Ω loudspeaker as an 8kΩ load, whereas the loudspeaker sees the Thévenin output resistance of the output valves stepped down by an identical amount. ...

There is not an exact formula for calculating the transformer turns ratio. Table 1 lists some empirically derived transformer turns ratio for a variety of CCFL lamps. As can be seen from the table, the transformer turns ratio decreases as the DC supply voltage increases, and the transformer tur...
The “ops : bytes” ratio R of the GPU, which is the FLOPS divided by the bandwidth in bytes/second (as measured by either memory reads or network bytes; we’ll assume for now that these are comparable). Ignoring multiplicative constants, the time for a forward pass is LR^3/C . This...
If the secondary windings are also connected Delta then they have equal voltages across each winding. Of course, this voltage will be either higher or lower than the primary depending upon the “turns ratio”. 480V Primary Source with 240V Secondary Output @ 2/1 Turns Ratio (Delta-Delta.) ...
