Hi Manoj,

What is the differences between EE type cores (ER-ETD-EE,etc) and toroid cores in class-d application ? because i think when we replace toroid cores with ee types , zobel network resistor becomes more warm..is it true ? can we reduce output HF with suitable filter ?

Regards

Hi IR,

not all toroid cores , only iron powder core with low AL value is good for class d(b'cause they have enough air gap) or toroid ferite core with 1.2mm gap is suitable for 500W RMS class d amp.

MANOJ

Thanks Manoj ,
