Class-D IRSound D200-V.0 Based On Apex D200 - a little music+ temperature test - YouTube

so , as i mentioned before , my amp have temperature problem
in this video , i used 48uH (5x0.5mm wire) on two stacked CSC CK270060 , the core was warm about 30~40 °C in all tests.
the loudspeaker is a 16 Ohm full-range paralleled with a 8 ohm Electric resistance wire. mosfets get hot during this test as you can see up to 50 °C.

please help me...why mosfets gets hot

Apenas fiz um comentario sobre a temperatura que o amplificador atingiu mas como assisti o video em baixa qualidade nao vi a virgula da casa decimal e pensei que fosse 550 C° desculpas

Just made ​​a comment about the temperature reached the amplifier but as I watched the video in low quality not seen the comma decimal point and thought it was 550 ° C excuses
