P-resonant control for the neutral point of three phase inverter
In this project, a Proportional resonant (PR) current controller is proposed to maintain a balanced neutral point for a three-phase four wire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional neutral leg and a split DC link. The neutral...

| description | In this project, a Proportional resonant (PR) current controller is proposed to
maintain a balanced neutral point for a three-phase four wire inverter, which can be
used in microgrid applications. The neutral-point circuit consists of a conventional
neutral leg and a split DC link. The neutral point is balanced with respect to the two
DC source terminals (as required, in neutral-point clamped three-level converters)
even when the neutral current is large so that the inverter can be connected to an
unbalanced load. The controller, designed by using the Proportional resonant control
techniques, which attain eliminate for the current flowing through the split
capacitors. This leads to very small variation of the neutral point from the mid-point
of the DC source, in spite of the possibly large neutral current. The simulation of
inverter circuit, neutral-point and P-resonant has been performed using
MATLAB/SIMULINK software. The simulation results confirm the validity of the
proposed method, which can be seen as a promising that ensure P-resonant control
suitable for microgrid applications. |
