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