Method and system for passive resonant voltage switching

Methods and systems for passive resonant voltage switching are provided. One passive resonant switching system includes a voltage switching system having one or more passive resonant modules to provide a switching voltage output. Each of the passive resonant modules include switching devices configured to operate in open and closed states to produce first and second voltage level outputs from a voltage input. The passive resonant modules also include a capacitor connected to the one or more switching devices and configured to receive a system discharge energy during a resonant operating cycle when switching an output voltage from the first voltage level to the second voltage level, and to be recharged when switching from the second to first voltage level. The passive resonant modules further include a resonant inductor and an additional switching device.
