Hi Infineon team,
Good day to you all, I'm working on a 2.5KW (Output - 58V 40A) Battery charger for EV Application. I've taken the 2Kw Li-ion charger for reference.
https://www.infineon.com/cms/en/product/evaluation-boards/eval_2kw_48v_char_p7/
Converter is working fine but I'm facing some heating issues in Output diodes. Kindly Advice me to solve this issue.
Output Diode specs : Vr - 200V, If - 45A, Vf - 0.86V output diode link - MBR90200WT
Here I'm attaching my primary transformer current waveform and output side diode current waveform for your reference

XDPS2221控制IC固件
REF_XDPS2221_140W板上的XDP™ XDPS2221已经升级到新的固件版本3.1.4。早期的固件版本不再被支持。XDP™ XDPS2221上的日期代码表示所使用的固件版本。图2展示了日期代码。
注意:如果REF_XDPS2221_140W板上的XDP™ XDPS2221的日期代码为2252,请升级该板。
升级使用固件版本3.1.4的XDP™ XDPS2221的REF_XDPS2221_140W1板的步骤:
-
订购新的XDP™ XDPS2221样品。联系你当地的Infineon销售人员,或联系Infineon支持。
-
用新样品(带有固件版本3.1.4)替换REF_XDPS2221_140W板上现有的XDP™ XDPS2221。
-
添加放电电阻。由于新的固件版本3.1.4不支持主动X-cap放电,你必须在输入端添加放电电阻;RX100和RX101(每个1.2 MEG)如图3所示
-
如果你要升级REF_XDPS2221_140W1板上的XDP™ XDPS2221到固件版本3.1.4,首先需要订购新的XDP™ XDPS2221样品。你可以通过联系你当地的Infineon销售人员或Infineon支持来完成这一步。
-
收到新的XDP™ XDPS2221样品后,将其替换到REF_XDPS2221_140W板上现有的XDP™ XDPS2221。这需要一些电子技术知识,可能需要使用焊接设备,并遵守安全操作规程。
-
新的固件版本3.1.4不支持主动X-cap放电,因此,你必须在输入端添加放电电阻。这意味着你需要在电路板上相应的位置焊接上两个放电电阻,型号为RX100和RX101,每个电阻的阻值为1.2 MEG。
左图:旧的REF_XDPS2221_140W板: 带有固件版本3.1.1的XDP™ XDPS2221, 没有放电电阻
右图:新的REF_XDPS2221_140W板: 带有固件版本3.1.4的XDP™ XDPS2221, 带有放电电阻
通过使用日期代码为2312的XDP™ XDPS2221,REF_XDPS2221_140W板将运行带有包括最新微调参数集的固件版本3.1.4。
注意:(可选)更新参数文件
如果带有固件版本3.1.1的REF_XDPS2221_140W板用于某些测试目的 在更换了固件版本为3.1.4的控制IC后,参数值已经发生变化,需要基于固件版本3.1.4的.csv文件使用你自定义的参数。
Show LessMy academic project involves implementing a wireless charger using the WLC1115 chip, which will perform authentication to ensure that the transmitter (Tx) can only be used with a specific receiver (Rx), and vice versa. To achieve this, I plan to use the OPTIGA Trust M chip. I have some specific questions related to this process and would greatly appreciate it if you could help me address them.
-
Which of the two methods for programming the WLC1115 chip do you recommend that is more easily accessible in the market and that can fully program the chip or modify its firmware?
-
Can I use the configuration tool provided by you for the basic configuration of the chip with the miprog4?
-
Can I use the chip without the Optiga trust charge but with the Optiga trust M?
-
Can I achieve a power greater than 10W without the Optiga trust charge?
-
What could I do if I want to transmit data between Tx and Rx?
- How can I program the Optiga Trust M?
Good day. I am developing an academic application which involves the development and implementation of a wireless charger with authentication. However, the authentication part mostly involves customizing the wireless charger for a single receiver (device). Initially, I relied on the WLC1115_68LQXQ chip, but the issue with this chip is that it is Qi 1.3 compliant, including authentication via Optiga, and I'm not sure if Optiga allows the authentication I require. I would like to know what ideas or recommendations you have for implementing the authentication of the wireless charger I need, or what other charging chip you would recommend.
Thank you.
Show LessMy name is Dexaca, and I am reaching out to inquire about the WLC1150 chip. I am looking to integrate this chip into a wireless charger for a project, and I require additional information regarding the corresponding receiver chip.
Furthermore, I am in need of the transmitter and receiver chip for authentication purposes during the charging process. If you could provide detailed specifications, compatibility, and pricing information, it would greatly assist in my decision-making process.
Additionally, I am interested in exploring other wireless charging chip options that adhere to the Qi 1.3 protocol for both transmission and reception of wireless charging. If you have any other product recommendations or references that meet these criteria, I would appreciate the information.
Thank you for your attention to this matter. I anticipate your prompt response and would be grateful for any assistance you can provide.
Show LessHi Infineon,
I am working on a 2.5KW battery charger and I have gone through the Application note of the Evaluation Board (2KW EVAL_2kW_48V_CHAR_P7) a Lead-acid/Li-ion battery charger of Infineon.
Here are my queries.
There is a resistor (R200) across the capacitor (C90) in the schematic but in the evaluation board that resistor is not present. But when I checked the current version of the schematic the capacitor C90 is not present. Can you explain this variation in schematics?
Show LessHi all,
I am testing PFC part of 2kW Charger Board. While testing the PFC part I am observing current spikes on AC Current at no load. I have checked the control part associated with PFC and Opam IC.
If I start to load it, there is a risk of MOSFETs getting damaged due to current spikes. What could be the reason for these spikes?
I have attached current waveforms on Oscilloscope, you can see the these spikes can go as high as 10A.
regards,
dev_ss
Show LessMay I ask if the output power of the EVAL_3K3W_BIDI_PSFB device in boost mode is limited, and if so, how can I lift the limit so that it can output full load power.
Please don't hesitate to teach me!

Show LessDear experts
I already use Infineon solution to design PD3.1 application.
and I have some questions about design document, please give me some suggestions, thanks.
1. how do you know the resonant period is Tr/2? could you please explain it more detail?
2. When should the secondary-side MOSFET be turned off, and how can this objective be achieved using open-loop control in SIMPLIS, I would like to use SIMPLIS to know the operation of AHB CRM mode, but it seems you don't have any simulation file in the website. if I use diode in the secondary is it ok?
3.Why is the waveform at the red-circled region different in these two images?
4. How to determine the dead time and the value of capacitor Cr?
5. How to optimize the CM noise in this topology? I want to modify it from the transformer side.
