Rectifier is the key component of a Wireless Power Transmission system. The optimal power conversion efficiency of a conventional rectifier can only be found at certain input power level. When input power shifts from optimal point, the efficiency drop rapidly. To overcome this, resistance/impedance compression network (RCN/ICN) is introduced in this report. When connected RCN/ICN to the rectifier, the resistance/impedance variation of a rectifier is significantly reduced. The matching performance of the rectifier with RCN/ICN is improved within wide input power range, resulting in efficiency enhancement. Other methods for extending input power dynamic range like power recycling technique are introduced, and a basic view of enhancing the efficiency when designing a rectifier chip is provided. |
