A single phase full bridge inverter has a dc voltage source Vs = 230 V. Find the rms value of the fundamental component of output voltage.

(a) 90 V

(b) 207 V

(c) 350 V

(d) 196 V

I have been asked this question in homework.

I would like to ask this question from Single Phase VSI-4 topic in division Inverters of Power Electronics

Correct choice is (b) 207 V

To explain: The fundamental component of voltage = (4Vs/π) sinωt.

Peak value Vm = 4Vs/π

Rms value = 4Vs/π√2.
