An electric vehicle (EV) charger can operate in an autonomous mode to create its own grid by utilizing the EV batteries during blackouts. This requires three-phase four-wire inverters as grid-side ac/dc port of supply unbalanced loads. Although silicon carbide (SiC) metal–oxide–semiconductor field-effect transistors (MOSFETs) be adopted increase power density these inverters, second-order rippl...

This paper presents a constrained multi-objective optimisation scheme for grid-connected voltage source converter operating under unbalanced conditions in three-phase three-wire system. The is aimed at evaluating the reference currents required to supply all power generated by connected grid, whilst simultaneously suppressing oscillations of both real and reactive powers. trade-off between thes...

this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...

This paper presents four types of time domain control techniques for generation of real time compensating current with a view to the problem of source current harmonics caused by non-linear loads in three phase three wire shunt active filters. All the techniques are analyzed mathematically and simulation results are compared in terms of compensation performance with multi parameter under steady...

Active power filter (APF) has now become a mature technology for harmonic and reactive power compensations in two-wire (single phase), three-wire (three phase without neutral), and four-wire (three phase with neutral) ac power networks with nonlinear loads. This paper presents a study on three different adaptive algorithms for active power filtering applications. These algorithms are adaptive l...
