hi i am studying electrical engineer and i am in final year,
my final project is about operating a three phase induction motor using single phase AC,
my contain three steps first AC source 220v to 220v DC using rectifier then making a variable DC voltage (0-220v)
using a buck converter the previous parts works fine but the big problem is how
to invert single phase dc to three phae voltage i search in my country
and i found an IC called IR2130 which helps me and i found an application and in it
there is a circuit for my project (i attach it) it contain a 555 timer for generating a PWM and
a shift register to generate a six PWM for the six mosfets i connect the circuit as on the application note
but i had a problem that the output of the(HO1,HO2,HO3)is constant voltage (is it correct??????????????)
and the output(LO1,LO2,LO3) are correct PWM i continue connecting the circuit , when i add a dc voltage
it seems that there is a short circuit i asked mysupervisor and a lot of peapole but no one helped me .
i will appreciate some help from and i will not forget it please answer me at my email <snip>
thanks
