About Power Choke
Comparing Iron, Alloy, Amorphous Powder Core just in few seconds and three steps get the best design in PFC, LLC, LCC. Of course, you can do it yourself, but if your time is more valuable, why not to save this treasure.
The power inductor is made by magnetic powder toroidal core with winding , also call DC-Choke, Power-Choke, sometimes depends on the circuit position is named PFC Choke, Inverter Choke, Buck or Boost Choke.
When the power is transferred more and more, the inductor current will change from discontinuous conduction mode to continuous conduction mode, and then the effect of this DC-Bias Current are going to derating the permeability of any magnetic alloy materials core.
How much of the inductance value is gone by the DC-Bias current ? That is the major problem of every engineers when the power choke is designed. Our App offers the visualized user interface, which deals with this issue and avoids the boring calculation process over and over again, allows you to find the best design factor working on the circuit just in few second, even compares each other with the second source.
The famous manufacturers of alloy powder core including CSC, Micrometals, KDM, Doungbu, POCO, DMEGC and Magnetics, all of them have been supported, and the permeability range are extended from 14µ to 300µ, so there are over than 210 types of core materials, that can be choose right now.
It will be more and more when the new version are going to release. Welcome to recommend any materials that you have often used, let us have the opportunity to make this App better. Thank you very much !

1. The LCC is the most common structure which compared with LLC, any points of view even from the master or expert, that would be not better than figured it out once here by yourself.
2. Still buying the expensive CAD, spending the time to learn how to build and debug just for LLC or LCC, why not to try this App and enjoy your money and time.
3. All technical consulted are from Texas Instruments.

1. The Y-Axis title in the LLC Voltage Gain should be "Vp/Vs" and it is corrected by this version.
2. There are three operational conditions need to achieve for the ZVS in the LLC, it is shown up when tap the first equivalent circuit cell.
3. According to the Fundamental Harmonic Approximation(FHA) analysis, the square waveform are transformed to the first harmonic sine wave, that should be have a gain and it is shown in the bottom of the Gain-Figure page.
