Testing at the application frequency, particularly with correlation, can be an extremely effective and superior method of determining the application suitability of a coil. The procedure to specify and the electrical test for an inductor at use frequencies is as follows: Specify the nominal inductance.
Thus, the power delivered to the inductor p = v *i is also zero, which means that the rate of energy storage is zero as well. Therefore, the energy is only stored inside the inductor before its current reaches its maximum steady-state value, Im. After the current becomes constant, the energy within the magnetic becomes constant as well.
Specifying and testing at the actual circuit frequency is an appropriate method of controlling inductor parameters. Use frequency testing ensures that components are consistent with their intended application. The primary inductor parameters are interrelated design functions of the coil.
The normal inductance is indicated at both frequencies along with their tolerances. If this coil had been specified as a 5% inductor at the test frequency, it would have resulted in a 10% tolerance at the application frequency. These limits could have compressed over frequency or spread even more, depending on the coil.
The inductor behaves like a load and stores energy to prevent ripples from producing excess current. It acts like a current supply when the ripple reduces the current value. In each case, the inductor prevents the ripples from influencing the regulated DC.
But the inductor's inductance value must be selected to perform both functions optimally. Large inductor values give low ripples and maximum power output. However, the value should not be too high because the inductors can get very bulky and provide a poor transient response.
