Abstract.
In this paper a new digital voltage controller based on the internal model
principle for three-phase inverters with ΔY transformer at the output is proposed. A dynamic model of the
inverter, transformer, filter and load is derived and a decoupling method is
proposed. The proposed digital controller is not prone to produce DC
components, which that can lead to the output transformer saturation. Additionally,
this digital controller result in a simple form and it is well suited for a
fixed-point implementation. Experimental results, implemented in 16 bits DSP
TMS320F241, validate the theoretical developments and demonstrate the good
performance of the proposed controller under both nonlinear balanced and unbalanced
loads.
