Abstract

Abstract

This paper proposes a novel motor-driving charging integrated topology with high-frequency AC link (HF AC-link), soft-switching operation and high-frequency (HF) galvanic isolation, which can apply to the two modes of motor driving control and charging. The topology belongs to a new class of resonant AC-link topology, and its link is composed of a series ac inductor/capacitor (LC) pair.When the topology is working in the forward direction, the driving motor is in the motor driving control state, and the battery is being charged in the backward working period. In this paper, the principle of operation of the two working modes of the new topology is introduced in detail. The effective control strategy is used and the simulation model is built by MATLAB/Simulink software. The integrated topology and control strategy are verified. The simulation results show that the topology works. The charging mode can meet the different voltage requirements of the whole charging phase of the battery; working in the motor driving mode, the stator current exhibits a good three-phase sinusoidal shape in both the acceleration process and the normal working process, and the rotation speed can reach a given value, thereby proving the feasibility of this topology and control strategy.
