Help with determining transfer function for a single phase inverter

Click For Summary
SUMMARY

This discussion focuses on designing a PWM controller for a single-phase inverter, specifically addressing the challenge of measuring current at the output leg instead of the inductor. The conventional approach involves two control loops: an inner current loop and an outer voltage loop, with current measured at the inductor and voltage across the capacitor. The user successfully resolved their issue by employing resistors in series and parallel configurations to adapt the measurement setup.

PREREQUISITES

Hello everyone.

So I have been tasked with an interesting take on what seems to be a classic problem, that is, designing a PWM controller for a single phase inverter. Now, in all the books I've read this problem has two control loops, an inner current loop and an outer voltage loop. The measured current is taken at the inductor and the measured voltage is taken across the capacitor (or the output). I understand this take on the problem.

However, my problem has everything the same as the classic one, except the current needs to be measured at the output leg. Any tips or if anyone can point me in the right direction would be very much appreciated.

Thank you very much in advance. Also if this isn't an appropriate place to post this question, let me know where I could.

Nevermind, figured it out using some resistors in series and parallel.
