Hello, I'd like to know if is possible and if is useful to use bias as second output? My design requer 5V/200ma Isolated and a 15V/200mA Non-Isolated (To drive IGBT). I try to simulate that in PiExpert but it was hard to converge to a solution. I appreciate a help

As this is a more detailed technical question, I did not want to bother the sales team with this: I am interested in using the mentioned GDU for an application with a 3,3 kV-SiC MOSFET. In the brochure, the GDU is labelled as SiC MOSFET ready. My question is: can

Hi, I have a 15W universal input design with INN3164C. In the past, I have seen some chips (like UCC28742 from TI, please see attached image for same design) use a ceramic capacitor for the bias winding output. To put things in perspective, PI Expert Web has specified Panasonic, EEH-ZA1V220R

使用TOP266EG设计一开关电源，输入220V，输出24V，完全按照PI expert软件的输出设计。目前现象是空载时，TOP266EG的D引脚一值维持大约320V电压，大约每隔1秒出现斩波波形，又立刻消失，输出电压大约为20V。如果带负载，电压立刻降低为3、4V。现上传原理图，请问是哪里的问题。谢谢。 此外，电路中的D1使用的FR307，与PI Expert软件的设计不一致。不接任何负载，输出悬空，TOP266EG依然会较热。

Could you please clarify what core material was used for this design? The core shape is clear but I couldn't see a part number for the core. Thanks!

How can I specify a split primary in PI Expert Web? PI Expert Desktop allowed this in the left panel under winding construction options. Thanks in advance. Best

Hi, As you know, the way that the dummy load resistors are wired for an EMC test can actually drastically effect the scan....the common mode noise can radiate off the dummy load wires , and indeed, from the dummy load resistors. Why did you not choose a more tight layout

Hi, Can we put both os these on the same heatsink? Would it give noise issues.

Hi, Please assist us in finding a DER report of a HiperPFS Boost PFC that uses sendust torroids (or other torroids)? We only see ones using ferrite core half type, with the associated bobbin. Why is this? Can't HiperPFS manage the non linear inductance of a torroid inductor?

Hi, Our load can be 300W, but at most for 5 seconds. The Load duty cycle is 0.26, so the average power is only 80W Vin = 100-265VAC, Vout = 37V Do you believe the HyperPFS PFC followed by the HyperTFS 2 tran forward is the way to go? We
