**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) =

φ φω

Where ω is the fundamental frequency.

Fourier series representation of output voltage,

V0n(t)=∑4VDCnπSin(nω)t

: where n= 1,3,5....

**Solution:**

The fundamental component of voltage =

π

Vo1(t)=∑4VDCπSin(ω)t

Peak value (Vm) = π 4Vsπ Vm π =4×240π

**Vm = 305.577 ≈ 306 V**
