The output voltage of a single-phase inverter is given by,
\({V_0}\left( {rms} \right) = \frac{{4{V_s}}}{{n\pi }} \times \frac{1}{{\sqrt 2 }}\)
Fundamental component of output voltage is \({V_{01}} = \frac{{4{V_s}}}{\pi } \times \frac{1}{{\sqrt 2 }}\)
Calculation:
Given that, input dc voltage (VS) = 48 V
Fundamental component of output voltage is \({V_{01}} = \frac{{4 \times 48}}{\pi } \times \frac{1}{{\sqrt 2 }} = 43.2\;V\)Last updated on May 28, 2025
