hi all,
i already make a boost converter for driving a load motor with specific : 200 v 9 ampere..
when the load is not connected the voltage can be up 200 v - 400 v but
when the load is connected the voltage output drop until below the input voltage
the output current is about 0.8 -1.1 A, also when i raise the duty cycle the output voltage can't be exceed to the input voltage.
i'm driving the mosfet with PWM from microcontroler
the input votage 15v - 30 v
induktor:100 µH
capasitor : 1µF 450 volt
mosfet :irf460
why the drop voltage si very high? is it because the cuurrent??
if the problem is the current how can i produce a bigger current??
