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.

“…So the power of APF is v p (9) If the second harmonic ripple is suppressed, the power of APF should be equal to the second harmonic input power. p (10) Then we can get the current and voltage of capacitor…”
