Simulation of voltage source converter based shunt active filter in EMTP‐RV
… source impedance and provide the necessary harmonic compensation for varying non-linear loads. This thesis models a Voltage Source Converter (VSC) based shunt active filter (SAF) to filter harmonics due to large non linear loads. SAF compensates the harmonics by injecting a compensating …

Mitigation of Asymmetrical Currents in Permanent Magnet Synchronous Machine with Unbalanced Stator Winding Impedance for Electric Vehicle Application
… in conjunction with the resonant controller and harmonic compensation terms in the inner current control loop of an interior PMSM (IPMSM) drive with stator winding impedance asymmetry. The harmonic-based resonant controller part of the PIR controller is used to compensate the harmonics of the …

New techniques to improve power quality and evaluate stability in modern all-electric naval ship power systems
… techniques, respectively. To mitigate harmonic currents generated by high-power high-voltage shipboard loads such as propulsion motor drives, the first paper proposes a novel seven-level shunt active power filter topology, which utilizes tapped reactors for parallel operations of …

Power Sharing and Power Quality Improvement in Parallel Connected Power Converters in the Microgrid
… LCL filter resonance and to compensate harmonics caused by nonlinear loads. These multi-functional requirements are putting challenges to VSC converter control. To address above issues, this thesis investigates VSC control methods that can effectively share the load power demand in …

Back to Back Active Power Filter for Multi-Generator Power Architecture with Reduced dc-link Capacitor
… scale power generating system to comply with harmonic regulations. Among all types of multi-pulse converters, a 12-pulse converter is the most widely used due to the simple structure, which consists of a delta-delta and a delta-wye phase-shift transformer pair and it effectively mitigates …
