A compact 2-terminal, series-pass active damping circuit utilizing semiconductor device is proposed. It is implemented with linearly-operated device such as MOSFET using current feedback control at very low dropout voltage. The damping device features a simple internal structure and is connected in series with a generic switching mode power supply (SMPS). It can damp unwanted oscillation due to the...
This study examines the P+ multi resonant based voltage control for the voltage harmonics compensation under the islanded mode of a microgrid. In islanded mode, the inverter is defined as a voltage source to supply the full local load demand without a connection to the grid. On the other hand, the output voltage waveform is distorted by the negative and zero sequence and current harmonics due to the...
