| Abstract |
The wireless power transfer (WPT) systems have to supply a stable output voltage to the battery. However, due to its physically separated structure and unstable communication control between transmitter-side (Tx) and receiver-side (Rx), there should be a battery control converter in front of the battery, causing a large number of components and low power density. To relieve these drawbacks, a new receiver-side post regulator (RSPR) with a simple control method and high power density is proposed in this paper. The proposed RSPR structure can help the WPT system to supply stable output to the battery. Besides, the proposed one can remove complex phase detection and unstable communication control method between Tx and Rx. Moreover, through the integrated single-switch into the rectifier diodes, high power density can be obtained. The effectiveness of the proposed structure is analyzed and verified experimentally by a prototype under 380VDC input and 250W output. |
