This study proposes a design method for a rectifier circuit that can be rapidly charged by focusing on the design-load value of the circuit and the load fluctuation of a storage capacitor. The design-load value is suitable for rapidly charging the capacitor. It can be obtained at the lowest reflection condition and estimated according to the circuit design. This is a conventional method for designing the rectifier circuit using the optimum load. First, we designed rectifier circuits for the following three cases. The first circuit design uses a load set to 10 kΩ. The second design uses a load of 30 kΩ that is larger than the optimum load. The third design utilizes a load of 3 kΩ. Then, we measure the charging time to design the capacitor on each circuit. Consequently, the results show that the charge time could be shortened by employing the design-load value lower than that used in the conventional design. Finally, we discuss herein whether this design method can be applied regardless of the rectifier circuit topology.
