Low power factor and increased current harmonic content are some of the negative effects of static power converters usage. To correct these disadvantages, active power filters with complex current control schemes can be used. This paper proposes an new method for tuning the resonant controllers also known as Proportional Sinusoidal- Signal-Integrator (P-SSI) controllers, based on Naslin Polynomials Theory.
