Welcome to the Infineon Developer Community

Hi all,

I am new for AURIX MCUs. Could you please help me with 3ph PWM generation, when over/undersampling condition could be requested on-line?

I assume I should use the GTM module, 3 (A)TOM channels to generate the switches control signals with the desired switching frequency and one additional (A)TOM channel to generate the PWM waveform with the desired sampling frequency to synchronise sampling/control ISR with it, but how can I synchronise my "switching" and "sampling" counters?  

Thank you!

Hello, 

I am building my prototype motor controller for a pmsm motor and i am following the infineon 22kw inverter reference design. In that design i have some doubts regarding the isolated gate driver power supply. I make a pcb for that module but i am not getting proper output . ( I bypassed the STO and gave 15 V to the 50% duty IC) .Can

someone explain that half bridge converter configuration used in the ref design, it will be very helpful for me

Hi I have just started working on psoc6 CY8CKIT-062S2-43012 in Modus tool Box and trying to connect Greengrass v2 edge device through MQTT.

I am unable to connect my psoc6 board to my edge device where I have installed Greengrass v2. I have used MQTT Client code from the examples of psoc6 CY8CKIT-062S2-43012 in modus Tool box, it is working fine when I am using endpoint of AWS IoT core. but when I am using the end point of my Greengrass v2 edge device then I am unable to connect. 

when I am using AWS Greengrass v2 SDK from AWS python code directly from terminal, then it is also working proper. 

please provide some support or examples if available for modus tool box.

Thank you in Advance

いつもお世話になっております。

以前にもICE3BR2280JZとICE5BR2280BZの許容消費電力に関して問い合わせましたが、

再度質問いたします。

ICE3BR2280JZの許容消費電力は下記のグラフになります。

ICE5BR2280BZの許容消費電力は下記のグラフになります。

以前にICE3BR2280JZとICE5BR2280BZのグラフの差は熱抵抗

96W/℃、104W/℃によるものと回答を頂きました。

しかし、グラフより周温80℃で比べると

ICE3BR2280JZは約0.72W、ICE5BR2280BZは約0.43Wです。

ICE3BR2280JZ

Tj=96W/℃×0.72W+80℃=149.2℃

ICE5BR2280BZ

Tj=104W/℃×0.43W+80℃=124.7℃

ICE3BR2280JZはTjが約150℃より、内部のMOSFET許容消費電力のため

ICE5BR2280BZより許容消費電力が0.29W(0.72W-0.43W)高いと考えたのですが

この理解は間違いでしょうか？

あと、ICE5BR2280BZのTjが約125℃になっているのはなぜでしょうか？

データシートにはコントローラーのTjは129℃記載されております。

 以上、よろしくお願いいたします。
