Three-Level Inverter-Based Shunt Active Power Filter in Three-Phase Three-Wire and Four-Wire Systems Abstract?AbstractThis paper presents a direct current-space-vector control of an active power filter (APF) based on a three-level neutral-point-clamped (NPC) voltage-source inverter. The proposed method indirectly generates the compensation current reference by using an equivalent conductance of the fundamental component using APF?s dc-link voltage…
Three-Level PWM Floating H-Bridge Sinewave Power Inverter for High-Voltage and High-Efficiency Applications Abstract?This paper presents a topology of a single-phase float-ing full-bridge three-level pulse width modulation (PWM) power inverter suitable for high-voltage/high-power dc?ac conversion. High power efficiency is obtained thanks to the slow (50/60 Hz) biasing of the H-bridge power supply terminals, allowed by a…
Three-Phase Grid-Connected WECS with Mechanical Power Control Abstract-This paper presents a grid-connected wind energy conversion system (WECS) based on a permanent magnet synchronous generator (PMSG) operating with variable speed. Considering that the wind has intrinsic intermittent nature, it is desirable to maximize the extracted energy, as a maximum power point tracking (MPPT) strategy is described…
Three-Phase LLC Series Resonant DC/DC Converter Using SiC MOSFETs to Realize High-Voltage and High-Frequency Operation Abstract?SiC MOSFETs are applied to constitute a three-phase, 5-kW LLC series resonant dc/dc converter with isolation transformers. A switching frequency of around 200 kHz for the transistors successfully reduces the volume of these isolation transformers, whereas insulatedgate bipolar transistors (IGBTs)…

Three-Phase Three-Level Flying Capacitors Split-Source Inver ters: Analysis and Modulation Abstract-Single-stage dc-ac power converters with boost capabilities offer an interesting alternative compared to two-stage architecture. One of the recently proposed single-stage dc-ac power converters is the split-source inverter (SSI). This paper extends the SSI topology from the two-level operation to the three-level one using the…
Three-Phase Transformerless Shunt Active Power Filter with Reduced Switch Count for Harmonic Compensation in Grid-Connected Applications Abstract-Shunt active power filter is the preeminent solution against nonlinear loads, current harmonics and power quality problems. APF topologies for harmonic compensation use numerous high-power rating components and are therefore disadvantageous. Hybrid topologies combining low-power rating APF with passive…
Three-Port-Converter-Based Single-Phase Bidirectional AC-DC Converter With Reduced Power Processing Stages and Improved Overall Efficiency Abstract-Single-phase bidirectional AC-DC converters based on three-port converter (TPC) is proposed for energy storage applications. Three power interfacing ports, i.e. a DC-bus port, a DC input port and an AC port, are provided by the proposed converter. A battery, whose voltage…
