    How to limit or reduce dc-dc boost converter ouput voltage?

    I have 12volts power supply and at the output of my boost converter circuit which consist of a 555 is 1200Volts eventhough the duty cycle is 70% at 1.2kHz.

    boost converter MOSFET overheat?

    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...
