Hey! I have problems building my own boost converter. It gives around 300V with duty cycle of 50, and if i lower the duty cycle to <10, i can get 5v, thats what i want. The problem is current: I can't get enough current from it. I have code that adjusts the duty cycle if voltage difference is detected. Duty cycle rises up to 60(i don't let it go higher, because overheat), and it gives me around 2V. What i should do? Does parts need upgrade or does that occur from wrong value of inductor? I don't have scope, so i can't really look the behavior of this circuit. I think it might oscillate at wrong frequency or something like that. Arduino code is kinda simple: (yeah, that is only the loop because there is nothing to see in the settings void (except DDRD = 1<<PD2
PORTD = 1<<PD2;
delayMicroseconds(100);
PORTD = 0<<PD2;
delayMicroseconds(100);
PORTD = 1<<PD2;
delayMicroseconds(100);
PORTD = 0<<PD2;
delayMicroseconds(100);
