1. According to customer suggestion, shows the relationship of DC bias current between "Oe" and "N".
2. Improved the "User eXperience", removed the empty materials in UU, EE, ER alloy core.
3. Fixed the bug, the ER core size can not reload when second tap.
4. We feel so sorry about those mistakes, any feedback and suggestion we will do something ASAP.

1. According to the customer's suggestion, the ER core has be supported from this version.
2. Reference the 2019 catalog of core manufacturer, the new materials and factors have been update.
2.5
2019-09-23
1. The core shape of UU and EE are ready for power inductor design.

1. The new resonant converter of "CLL" structure, which has been supported from this version.
2. Compare CLL with LLC or LCC just in a few seconds.
2.3

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.

1. The equivalent circuit of LLC is built for understanding how to get the voltage gain from the LLC resonant tank.
2. How is the LLC voltage gain affected by the Lr, Lm and Cr ? The interactive UI let you got it just one look.
3. All references are from Texas Instruments Power Supply Design Seminar 2018.

1. Three steps find the best design in your PFC application. First choose the core size, the second selected what materials you want and finally click the PFC circuit !!! Done, no more !!! Only start from this version.
2. Two major manufacturers in China DMEGC and POCO, all of their materials have been supported from this moment.
3. Thanks to the Germany SMA Engineer, he points it out the bug about the initial inductance and we feel so sorry about this mistake.

1. The new generation materials of Amorphous Powder Core has been supported by Rev1.9 , that core loss is less when switch frequency is higher, so welcome to compare !!!
2. The core materials are grouped in different colors , Blue is for alloy powder core , Black is for iron powder core and Green is for amorphous powder core.

1. The materials of Iron Powder Core have be built in Rev1.8. If you want to compare the iron powder with alloy powder, update it right now !
2. Modify the H's range from 25~950 Oe in the curve of DC-Bias V.S. µ% .

1. According to the core loss, the core temperature rising is evaluated without fan cooling condition.
2. The materials of Korea famous manufacturer "DONGBU Metals" are all supported from this version, because it is suggested by our regular customer in Republic of China.
3. There are 150 alloy materials can choose right now and will be more in the future. Please recommend any manufacturer you use often, we will combine it in our App as soon as possible.
