I got this SSH7N90 MOSFET which is 7 amp 900 volt in a TO-3P. hooked up in this boost converter circuit. Its running at 1kHz. I used a 9v 175 Ni-MH rechargable battery and got it to work producing 800 volts. After 1 minute, the MOSFET still remains room temperature and the circuit is functioning. So i just bought this battery to increase the rate of charge of this boost converter for capacitors. Its a 11.1V 2200mAh 3 cell Li-Po battery with ratings of 30C and burst of 50C. I figured it would be a better alternative than buying many rechargable 9 volts battery which would cost more expensive. I use it in my circuit and the MOSFET reaches a burning skin temperature within 2 second of being turned on.
Problem is, i need it to work for 15 seconds before being so incredibly high in temperature so i can just finish charging the capacitors.Any recommendation or tips to reduce this drastic rise in temperature? Need detailed explanation please. Thanks
PLUS the circuit does not create high voltage with the battery i bought. but when i switch back to my 9 volts, it works again. Li-Po batteries not compatible maybe?
