Hi. I am new to this. I am 40 years old. I have a Bachelor's degree in Electrical and a Master's degree in Digital Signal Processing. I am looking to do a PhD in Power Electronics in Europe. I would like to know what my chances are.

Thanks.

Hi, I'm afraid I can't tell you  your chances, but I suggest you look at available PhDs in this area and perhaps contact the supervisors:
