CPC H02J 50/12 (2016.02) [H02M 7/5387 (2013.01)] | 20 Claims |
1. A wireless power transfer (WPT) system comprising:
a compensation network for reducing reactive power in the WPT system, the compensation network comprising:
a series/series (S/S) constant current (CC) source comprising a transformer and a S/S compensation network for the transformer, the S/S compensation network consisting of a first compensation capacitor and a second compensation capacitor, the first compensation capacitor being connected in series with a first inductor on a primary side of the transformer and the second compensation capacitor being connected in series with a second inductor on a secondary side of the transformer, the first compensation capacitor, the first inductor and a mutual inductance of the transformer configured for resonant operation at a defined frequency, the S/S CC source converting an input voltage signal of the WPT system into a constant alternating current (AC) current signal at the defined frequency; and
a constant current (CC)-to-constant voltage (CV) network comprising at least a third capacitor and a third inductor, the CC-to-CV network configured for resonant operation at the defined frequency, the CC-to-CV network converting the constant AC current signal into a constant AC voltage signal at the defined frequency.
