This paper presents a novel modelling technique which makes it possible to represent the overall inverter nonlinear error voltages by a simple analytical formulation. The proposed model architecture allows to consider multiple input variables in addition to the conventionally used phase current including the switching frequency and dc-link voltage. Based on the model, a highly efficient error voltage compensation can be achieved for an entire operation range of a voltage source inverter which makes it especially suitable for high performance industrial AC drives and photovoltaic applications.
