摘要

The electrification of transportation equipment have a high impact on the power grid, especially when the electric energy is used as its power source, the power conversion of the charging equipment will produce a large amount of harmonics. In order to reduce harmonics and improve operating power factor of the charging system, we select a specific circuit topology based on analysis of the operating characteristics of this type of charger, and carry out theoretical analysis and simulation verification. On these foundations, the prototype of charger is made and closed-loop debugging is carried out, the experimental results show that the output voltage of the prototype is adjustable, the grid-side current is undistorted, and realized a unit power factor operation.
