There is an interesting article in the 22 November 2018 issue of Nature magazine, starting on page 532, on a model airplane propelled by the ionic wind from an array of electrodes driven at 40 Kilovolts DC.
.. . Fig 1 has the circuit diagram.
The electrical system consists of a 160 to 225 Vdc LiPo lithium battery pack feeding a H-Bridge series-parallel resonant inverter that drives a 15:1 center-tapped step-up transformer that in turn drives a pair of six-stage Cockcroft-Walton voltage multipliers that yield +20 KVdc and -20 KVdc, total drive being 40 KVdc.
