1-phase Full Bridge Inverter with R- Load
1-phase full bridge inverter with resistive load Ri it has advantage over 1-? half bridge inverter that it does not requires 3 wire de supply and the amplitude of output voltage is doubled than output voltage of half bridge inverter.
When thyristor T1 and T2 turned on with ig and ig respectively the output current i flows through Vdc T1 and T2. The output voltage Vo = V dc is obtained.
With the help of neat sketch T-S diagram illustrate the working of simple air evaporative cooling system used in air craft. With the help of neat diagram and T-S diagram iillust
