Circuit and Waveform diagram, Operation
The number of SCR's and diodes is twice of the count of the half-bridge inverter.
FULL-BRIDGE
INVERTER
The
figure below represents the circuit diagram of a single-phase full-bridge
inverter:
Figure
shows the four SCR's and four diodes in the configuration. the number of SCR's
and diodes is twice of the count of the half-bridge inverter.
The
circuit operation takes place for a time duration between 0 to T/2, SCR's T1
and T2 are triggered by gate pulse thus the two conduct and the load
voltage will be V i.e., equivalent to the supply input. While for time instant
between T/2 to T, SCR's T3 and T4 begin to conduct as
gate pulse is removed from T1 and T2 and provided to T3
and T4 at instant T/2.
The
waveform representation is shown below:
The
operation is similar to that of a half-bridge inverter but the difference here
is that the amplitude of output voltage is double in this case
