    Single Phase Full Bridge Inverter:

    Single Phase Full Bridge Inverter is basically a voltage source inverter.

    Single Phase Full Bridge Inverter requires a two-wire DC input power source suffices the requirement.

    The output frequency can be controlled by controlling the turn ON and turn OFF time of the thyristors.

    The gating signal and an output voltage waveform of a single-phase full-bridge inverter are shown below:

    Formulas:The conduction angle of each diode is φ.The conduction angle of each Thyristor is (π – φ)

    Self-commutation is possible only in leading power factor load or underdamped system at circuit turn off time (tc) =
