kernel_task triggers when I connect the power adapter

Hi,

I have a problem with my Retina MBP, when I connect the power adapter, kernel_task starts to consume between 200% and 300% of CPU.

I have tried with:

• Reinstall the OS: without success
• Reset SMC: without success
• Safe boot: without success
• Create another user profile: without success
• NVRAM reset: it works partially, because when I stop using my MBP around 5-10 minutes, kernel_task returns to consume 200% - 300% of CPU (this does not happen if I disconnect the power adapter)

PD: Apple hardware test shows no error.

I hope you can help me, thank you very much!
