High-frequency High-voltage Class-E DC-AC Inverter

In this research, a high-frequency high-voltage inverter based on class-E amplifier is presented. The inverter utilizes a high-ß series resonant network to obtain high voltage with amplitude 2 kV at operating frequency 1.5 MHz. Due to high-ß network, it was possible to obtain high voltage at output without transformer. The proposed generator was calculated, simulated, built and tested. The experimental voltage amplitude amounted to be 2kV with DC power 31W at operating frequency 1.5 MHz.
