To avoid weight, size and cost constraints, on-board integrated charging devices use the traction system components. In this paper, the topologies of on-board integrated electric vehicles (EVs) chargers are reviewed. The topologies of on-board integrated chargers can be classified into three groups based on the integrated components. The first type is that only converter is integrated as one part of the on-board charger. While the grid side also needs filter inductors. The second group is based on the switched reluctance motor, which can integrate both the converter and the motor windings into the on-board charger. This is followed by the integrated charger based on permanent magnet motor (PM) and induction motor (IM). The last group also integrates both the converter and the motor windings. Then this paper gives a new single-phase on-board integrated charger based on AC motor. Parts of inverter are used as single-phase rectifier, parts of inverter coupled with one capacitor and inductor reconstruct an active power filter (APF) circuit, and the motor windings are used as grid-side filter inductors. As the existence of APF circuit, the proposed integrated charger can eliminate the second harmonic ripple and the quasi-Z-source network just need small capacitor and inductor to suppress ripples. Using the proposed topology, the motor can keep still in charging mode. A 2.2-kW prototype is designed to give the experimental results.Index Terms-Active power filter (APF), integrated charger, quasi-Z-source.

Summary This paper describes an empirical mode decomposition control algorithm to extract the fundamental component and set the reference for harmonic extraction in a cascaded multilevel inverter–based shunt active filter. The proposed technique is fully reliant on the data samples that are decomposed instantaneously and does not require any weighing factor. The fundamental component of load current is found by applying a novel empirical mode decomposition algorithm from the nonlinear load current samples. Spline interpolation is used to extract the intrinsic mode function. For online implementation, the maxima and minima points of load current are stored using a modified field programming gate array (FPGA)‐based circular buffer circuit. Finally, the proposed cascaded multilevel inverter–based shunt active filter is investigated both by simulation and hardware implementation. The results obtained validates the performance of the proposed control technique under balanced and unbalanced loading conditions.

“…Some literatures devoted to introduce new topologies of multi-input inverters [34][35][36][37][38][39]. Some of these introduced a multi-input inverter which is suitable for single-phase applications [36][37][38][39] and the others are suitable for threephase applications [34,35]. Liu et al [34] has employed double-stage energy conversion method for producing a three-phase output from two DC inputs.…”

“…This method is simple for implementation but the total system have more cost, size, weight, loss and etc. Singh et al [35] has used single-stage energy conversion method. This method is better than double-stage energy conversion method but complexity increase is an issue in this situation.…”

Multi input-multi output Power electronic interface for hybrid energy resources has gathered much of interest. In this paper, a new configuration for cascade connection of two Z-Impedance networks is presented which is able to extract power from two separate low voltage energy sources such as photovoltaic panels and fuel cell stacks. The required load power can be shared between two sources which may have different low values. The power sharing is controlled by adjusting the shoot through duration and time shifting. The proposed converter includes the features of conventional Z-source converter such as voltage boost and shoot through immunity of the inverter. Steady state operation principles, switching methods and the main relations for power flow from two inputs to the output are derived. A prototype of the converter is built and tested for different operation modes. The results are compared with simulations and theoretical analysis which verify well performance of the system.
