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
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
