| Summary: | The synchronous inverter is an electrical inverter
device which is synchronizing inverter phase into the microgrid
phase at the same amplitude and frequency. A three phase
phase synchronous inverter (PSI) is basically used in the high
efficiency power supply systems. The inverter phase is depend
on the controllers which are two level pulse width modulation
(PWM) generator, phase lock loop (PLL) regulator, DC
voltage regulator current regulator and Uref generator to get
the reference input and output voltage and current for
synchronizing the phase angle. An inverter using a three leg
IGBT has been designed for microgrid systems and simulated
by using MATLAB2014a. The input and output lowpass LC
filters are used to synchronize the micro-grid phase. The
controllers have generated PWM signal and a zero crossing
sampling is used to precisely synchronize with microgrid line
frequency. A balanced microgrid load of star configuration
(00, 1200 and -1200 degree), and also the input DC voltage ±
250V are considered in this design. The overall conversion
efficiency of the PSI is 97.62% and phase synchronization
error for each phase is about 0.50, 1540 and 2650 degrees. The
results show that the design has better performance and can be
used efficiently in the micro-grid system. |
