5. Conclusion

For many WPT applications, the voltage doubler is the preferred rectifier topology. This book chapter has outlined the operating principles of voltage-doubler rectifiers and has presented the most important design considerations for the implementation of such rectifying devices as standalone circuits. It has also presented examples of the use of voltage-doubler rectifiers as part of a directive rectenna system and as part of an energy harvesting system where a voltagedoubler rectifier was cascaded with an active DC-to-DC booster, demonstrating the successful implementation of wireless power transfer systems using voltage-doubler circuits as the preferred rectifier topologies.
