A single-phase full-bridge voltage source inverter is operated in 180° mode with square wave output. If the input DC supply is 100 V, the RMS value of the fundamental output voltage is

### Right Answer is: 90 V

#### SOLUTION

The fundamental value of the output voltage is given as

${V_{out\left( {_{fundamental}} \right)}} = \frac{{2\sqrt 2 }}{\pi }{V_{dc}}$

= (2√2 × 100)/3.14

Vout fundamental = 90 V
