Question

Find the peak value of the fundamental component of voltage with a pulse width of 2d = 90 and Vs = 240 V for single-pulse modulation in a full wave bridge inverter.

(a) 305 V

(b) 216 V

(c) 0 V

(d) 610 V

I got this question in quiz.

The doubt is from PWM Inverters-1 in section Inverters of Power Electronics

Answer 1

Correct option is (b) 216 V

To explain I would say: The peak value of the fundamental component of voltage is given by (4Vs/π) sin d.
