一种基于双有源桥DC-DC变换器且无需内电流环的单级自然功率因数校正器

In this article, a single-stage ac-dc based on the dual active bridge with natural power factor correction is proposed. A modulation strategy and a control technique have been given to achieve the unity power factor of the ac side without inner current tracking loops and lookup tables. A notch filter is used in the output voltage feedback path to reduce the influence from the low-frequency output-...
