“…Therefore, the commutating functions of the two inverters have to be determined in order to achieve the above results. In [7] a predictive approach has been proposed, which carries out the commutating functions determination of both the main and filtering inverter to achieve not only a perfect tracking of the desired motor current, but also a high efficiency power sharing between the two inverters. The feeding algorithms based on predictives approaches are characterized by several difficulties related to the off-line and on-line identification of the system parameters.…”

“…This solution allows obtaining high quality currents but introduces an increase of the system cost, weight and complexity. In [7] the control of common mode currents is solved without the introduction of insulation transformers but connecting the filtering inverter to an insulated capacitor charged directly by the main inverter, by using an appropriate voltage loop. It has to underline that by using this solution all the power required by the load is provided by the main inverter while the filtering inverter can be only used to increase the motor current quality.…”

“…Further analysis, shown in this paper, prove that the most part of the problems, related to the currents circulation between the main and the filtering inverter, can be minimized adopting an high performances current control. In [5] a DSP (Digital Signal Processor) based current control is performed while in [6], [7] a predictive current control is proposed. The solution proposed in [5] can, in theory, control very well the motor currents but its performances are compromised by the low switching frequency imposed by the DSP.…”

Motor Side Active Filter (MSAF) is a novel solution for high performances or high power motor drives. It is based on the parallel connection of two or more Voltage Source Inverter (VSI) controlled with an active filtering approach. In this way an optimized power sharing can be performed. This approach can be used to improve the converter efficiency in application where either high power or high switching frequency is required. In this paper special attention is paid to the hardware implementation of the MSAF on a low cost and high performances FPGA (Field Programmable Gate Array) based control system. Experimental results are given and discusses.
