Improved Selective Frequency Active Damping for Voltage Source Inverter With Output LC Filter

Stand-alone applications employ voltage source inverter with output LC filter to provide a high-quality ac supply at load terminals. These typically use filter inductor current as feedback to actively damp the LC resonance. But it also magnifies the output impedance of the inverter and, thus, deteri...
