A high voltage pulse generator is disclosed. The high voltage pulse generator comprises a pulse generating transformer having a primary coil with a first side and a second side, and a secondary coil with a first side and a second side. A direct current (DC) voltage source connection is at the first side of the primary coil. A first high frequency power driver transistor is coupled between the second side of the primary coil and a ground connection. The first high frequency power driver transistor is configured to operate in an on-mode for a selected time period to charge the primary coil for the selected time period based on a switching frequency of the first high frequency power driver transistor, and switch the first high frequency power driver transistor to an off-mode at the switching frequency to release the charge from the primary coil to the secondary coil. A diode is coupled between the first side of the secondary coil and a pulsed voltage output that is configured to be connected to a high voltage device. The diode configured to direct a flow of charge from the secondary coil to charge a capacitance of the high voltage device to a rising pulse leading edge of a voltage pulse.
