Resonant rectifiers have important application in very-high-frequency power conversion systems, including dc-dc converters, wireless power transfer systems, and energy recovery circuits for radio-frequency systems. In many of these applications, it is desirable for the rectifier to appear as a resistor at its ac input port. However, for a given dc output voltage, the input impedance of a resonant rectifier varies in magnitude and phase as output power changes. A design method is introduced for realizing single-diode “shunt-loaded” resonant rectifiers, or class E rectifiers, that provide near-resistive input impedance over a wide range of output power levels. The proposed methodology is demonstrated in simulation for a 10:1 power range.
