Research on the high power cyclotron-wave rectifier

As a key component of a Wireless Power Transmission System, a cyclotron-wave rectifier, a high power microwave to DC converter, has received more attention from scholars. This paper comprehensively analyzes various limiting factors of the output voltage and current. The results show that high frequency breakdown, the external magnetic field, and engineering realization limit the output voltage, and the space charge force limits the beam current. On this basis, by using the equivalent circuit and particle simulation, we design a cyclotron-wave rectifier with high power. The simulation results demonstrate that working at 2.45 GHz, the rectifier can obtain an output voltage of 113 kV and an output power of 791 kW. These conclusions can provide guidance for designing and application of this device. Published by AIP Publishing.
