| Summary: | The inverter is a power electronics device which
changes DC voltage to AC voltage or vice versa. The
synchronous phase inverter is used in the microgrid system to
connect the renewable energy sources of minimum phase
error. For a high-efficiency power transmission and
distribution system, a three-phase inverter is used. The
electronic switches of the inverter are controlled by a
controller circuit which can be a two-level pulse width
modulation (PWM), phase lock loop (PLL) controller, etc. A
fixed reference DC voltage and current generators are used for
a stable input-output voltage and current to reduce the higher
harmonic distortions. An LC lowpass filter has been designed
and simulated for the input and output of the system by using
MATLAB2014a. The input filter is utilized to reduce the AC
ripple component in the DC input supply, and the output filter
is used to reduce the higher frequency harmonic distortion
from the inverter output supply to maintain the IEEE
standard THD < 5%. A balanced microgrid star configuration
load and the input DC voltage of ± 250V have been considered
in this design. The overall conversion efficiency of the inverter
is 97.62% and THD <5%. The results show that the design has
better performance and can be used efficiently in the microgrid
system. |
