Power Electronic equipment that converts a DC
power into AC power at required voltage and frequency level is
known as Inverter. Voltage Source inverters produce an output
voltage or current with levels either zero to positive voltage or
zero to negative voltage that means two levels. These bi-level
inverters are powered by different type of gating signals like
square, quasi – square and sinusoidal Pulse width modulated
signals. Different gating signals result in different harmonic
levels in the output signal. In this paper, a hardware prototype of
a single phase inverter using MOSFETs as the power switches
has been developed. The MOSFETs are driven by square and
quasi-square gating signals. These gating signals have been
generated by designing the driver circuit using a MOSFET
driver IC. In order to maintain the voltage level, the conduction
time interval of MOSFETs has been maintained by controlling
the pulse width of the gating pulses. Performance of the inverter
has been studied for resistive load. Simulation has been done in
SIMULINK, results of simulation and experimental model has
been compared on the basis of various parameters like output
voltage, load current and THD levels.
