Abstract	A four-leg distribution static compensator (FL-DSTATCOM) has been employed for improving the quality of power in electric distribution system using field-programmable gate array (FPGA). A predictive current control technique without any modulation scheme is utilised to generate switching pulses for FL-DSTATCOM using a cost function defining the preferred system behaviour. This technique makes the supply current as balanced and sinusoidal by exactly tracking the reference current, compensating the reactive power, maintaining near unity power factor and nullifies the current flow in neutral conductor during steady and dynamic state conditions. Synchronous reference frame theory is effectively implemented for extracting the reactive and harmonic part of load current which are the primary components in the evaluation of reference currents. The predictive current control scheme implemented in FPGA has been deployed to evaluate the behaviour of the FL-DSTATCOM under multifarious loading conditions.
