This paper presents a novel current control method for three-phase APF based on switched affine system quadratic stability. In this paper, three-phase APF is modeled as switched affine system. The three-phase grid voltages are divided into 12 regions, each region has chosen a combination of switching subsystems according to the condition for quadratic stability. By selecting the common Lyapunov function...
This paper presents a new harmonic measurement scheme on lifting wavelet transform based adaptive filter (LWTAF) for active power filters (APFs). As one of methods to build second-generation wavelets, lifting wavelet transform (LWT) can be easy to achieve in time domain for its original bit location calculation. LWT could lessen calculation complexity and depress course due to its particular structure,...
