A single-inductor dual-output wireless power delivery system for small size battery-less NAND flash memory card is presented. The power delivery system uses two rectifiers connected to a single inductor which is synchronously switched by pseudo-random-sequence PWM signal with induced AC voltage. The power delivery system can generate 8 V and 16 V with peak efficiency of 40 % and maximum total transmitting...
A single-inductor dual-output wireless power delivery receiver for small size battery-less applications is presented. The power delivery system uses two rectifiers connected to a receiving inductor switched by pseudo-random-sequence PWM (PRS-PWM) signal synchronized with induced AC voltage in the receiving inductor. The power delivery system can generate 8 V and 16 V with peak efficiency of 40 %....
Recently, many applications have emerged that use wireless power delivery technology. A new standard “Qi” [1] has been established for battery operated portable devices. The rechargeable battery acts as a power buffer and shields the rapid load variation. Therefore, the requirement of the response to load variation is not so stringent and time constant of the power control loop is longer than several...
