Abstract
A resonant DC-DC converter for generating high voltage MHz bi-polar DC pulses includes a left multi-level resonant rectifier bank [] connected to a positive electrode [] and coupled via capacitive isolation to a left RF amplifier terminal []; a right multi-level resonant rectifier bank [] connected to a negative electrode [] and coupled via capacitive isolation to a right RF amplifier terminal []. Each multi-level resonant rectifier bank comprises multiple resonant rectifier stages [-], where each stage comprises two capacitors for capacitively isolating the stage, an output capacitor, a MOSFET switch connected to an adjacent MOSFET switch of an adjacent stage, and a gating resonant circuit connected to the MOSFET switch, whereby MOSFET switches in the banks can be passively controlled by RF signals from a left RF amplifier and a right RF amplifier.
