A control technique of direct current control and harmonic distortion work ,similar as the control of active power filter (APF), is proposed utilizing a new kind of electric springs (ESs) with current-source inverters (CSIs) to improve the working of ESs. The total harmonic distortion (THD) can be reduced greatly by changing voltage source inverters (VSIs) to current source inverters (CSIs) and by using fuzzy logic controller. By introducing extra Harmonic Suppression Function (HSF), the System execution can be enhanced further by resolving the input current into fundamental component and other components by using single-stage dq0 technique. Working standards of the proposed ES and control are illustrated.
