摘要

提出了一种由全桥变换器组成的单级交直流变换器,用于电动汽车充电。该方法优于目前广泛应用于电动汽车充电器的传统两级ac-dc变换器。两级交直流变换器造价高,体积大。然而,单级ac-dc变换器适合于低成本,小体积,因为减少了组件数量。该方法实现了从轻负载到重负载的高效率转换。它也实现了高功率因数在满负荷状态。本文通过0.8kW / 1.6kW产品样机的实验结果验证了该方法的可行性和实用价值。

Single stage AD-DC full-bridge converter for battery charger
A single-stage ac-dc converter consisting of full-bridge converter is proposed for EV charger applications. The proposed approach is superior to conventional two-stage ac-dc converter widely used for EV charger applications. The two stage ac-dc converter is apt to be costly and large. However a single-stage ac-dc converter is suitable to a low cost, small volume due to a reduced number of components. The proposed approach achieves the high efficiency from the light load to heavy load conditions. It also achieves the high power factor at the full load condition. In this paper, the feasibility and practical value of the proposed approach are verified by the experimental results from a 0.8kW / 1.6kW products prototype.
