I made a boost converter with 1 1mH inductor, a mosfet, a 100uF capacitor rated for 400v, a 20 ohm 1/2 watt resistor, and an ICM7555 cmos timer.
Using previous knowledge and wikipedia pages on the subject, I assumed that my volt6age should be brought from a 5v input to 10 volts. I assumed that the inductor effectively became a battery in series with the source. After seeing a ridiculous (and continuously rising) voltage, I became suspicious.
What is going on? I not getting 10 volts, but I am rather getting a continuously rising voltage. My mosfet is rated for 55 volts so I haven't been testing above that, but it rises steadily until I disconnect it at 50 volts. If anyone could take the time to explain what is going on, that would be great.
*NOTE : My 555 timer is connected with unknown capacitors (small) as C and a 1k as Rb and a 10k as Ra.
EDIT : For clarification, I changed "but it rises steadily until it reaches 50 volts" to "it rises steadily until I disconnect it at 50 volts"
