| Summary: | The inverter converts electrical signal from DC to AC by using power electronic
circuits. Inverter output is square waves and a filter is needed to change the output to
a sinusoidal wave. A control method is implemented in this project to create stable
sinusoidal voltage amplitude. The benefit of using control method is the inverter can
be adjusted to adapt to a variety of loads and able to mitigate any small disturbance
in the system. PID controller is chosen for this project because the PID controller can
solve a very complex control for nonlinear element. The PID controller is developed
in Matlab Simulink simulation and coded into TMS320F28335 board. In
TMS320F28335 board, the desired voltages are compared with the output voltages to
get the error signal that will go into the PID controller. SPWM signal is created by
using the correction signal from PID controller and fed to the three-phase inverter
with filter to give a sinusoidal output. Based on the result obtained, the three-phase
inverter has successfully created a stable sinusoidal voltage output for any given
