| Summary: | The inverter is an electrical switching control device
that can be converted from one source to another source like as
DC to AC or AC to DC. An efficient three leg IGBT inverter
has been designed for microgrid systems which are simulated
by MATLAB2014a /Simulink. The inverter switches are
controlled by a pulse controller, which mainly generates the
switching gate pulse. The switching pulse controller consists of
two level pulse width modulation (PWM), phase lock loop
(PLL), DC voltage and current regulator and Uref generator.
The inverter gate pulse has designed using the input reference
voltage and current, output reference signal and a reference
phase angle. The pulse signal precisely synchronized with the
microgrid line frequency of zero crossing sampling and
reduces the total losses in the inverter which is almost 50W.
Two lowpass LC filters have been used in this inverter that
reduces the switching loss. The design of the three-phase
inverter has better performance compared to single phase; the
overall conversion efficiency of the inverter is 97.62%. |
