摘要: This paper presents a control for universal active filters derived from the current-shaping strategy previously employed shunt filters. It operates with reduced number of sensors, using only two AC and one DC real time measurements. The proposed solution has natural mitigation capability nonlinear loads, which can be further improved quasi-resonant scheme. resulting energy flow tracking is designed robust framework, guaranteed stability optimal performance predefined range operation. Experimental results are presented 1kVA prototype.
