Abstract

Here, a grid voltage sensorless control of an LCL-filtered LC-tuned single-phase shunt hybrid active power filter (HAPF) is proposed, which offers high-quality harmonic current compensation with low hardware requirements. An estimation algorithm replaces the grid voltage sensor and associated circui...
