The next control objective is to ensure the DC link voltage to a
constant value in order to flow maximum power to the grid.
This is also essential for an undistorted sinusoidal current
injection to the grid by the inverter. This paper proposes a
simple yet effective maximum power flow controller to
achieve this objective. The output voltage of the boost
converter should have the proper coordination with the 60 Hz,
208 volt grid. The basic principle of the proposed maximum
power flow controller is described as follows:
