| Summary: | Rectifiers are essential for microwave wireless power transfer (MWPT). RF-DC conversion efficiency must be improved for the practical use of MWPT. The focus of this research is related to single shunt rectifiers. Former research explained the operations of single shunt rectifiers in the frequency domain. Currently, we are using a harmonic balance method for the circuit simulations. These analyses focus on the frequency domain and transient phenomena were not directly analyzed. Also, the differences between experiments and their simulations are still issues in designing rectifiers. Therein, we analyzed an ideal rectifier with transient analysis and simulation. We also propose a novel simulation for single shunt rectifiers. Our simulation method is based on simple theories focusing on the steady-state condition of transient phenomena. In our analysis method, the output DC voltage is a fixed parameter and the DC current with the voltage is calculated. Therefore, this method is suitable for analyzing I-V characteristics. First, theoretical solutions are compared with Advanced Design System (ADS) simulations and they show the good agreement. Next, we created the novel simulation with our analysis method. Their results are also compared with ADS simulations. These analyses showed good agreement. Therefore, our novel method is consistent with former researches and commercial simulations. As a result, this research shows a novel analysis method for single shunt rectifiers and its consistency.
