Hello,

I am building a step converter, the circuit works and is based on the
following web site:
http://services.eng.uts.edu.au/~venkat/pe_html/ch07s3/ch07s3p1.htm
My circuit boost from 5v to 150v, bit it takes about 45 seconds to
reach the maximum voltage with the proper duty cycle. I found out by
using a bigger coil I get a faster result. Is there a way to reach the
150v within 10 seconds or less? or is this how it usually works and we
cannot do anything about it..

Use a push-pull converter configuration for a much faster response time.
