| Abstract(in English) | This paper presents a design of the closed-loop thinned-out controlled class-E rectifier. It is possible to realize both thinned-out control and the PDM one at the same control-circuit topology. In addition, fine output-voltage controls can be achieved because the control circuit can make a thinned-out signal at any thinned-out ratio. For evaluating the proposed class-E rectifier, the resonant dc/dc converter with the class-DE inverter and the proposed class-E rectifier is designed and implemented. The control characteristics of the resonant converter were measured for load and input-voltage variations. It is seen from the experimental results that the thinned-out control provides higher efficiency than the PDM control. In addition, the power spectrum of the switch voltages suggested that the cutoff frequency of the low-pass filter for thinned-out control can be higher than those for the PDM control, which contributes circuit-volume reduction. |
