  • High voltage magnetic compression modulator
    Patent number: 7459806
    Abstract: A high voltage magnetic compression modulator including a low-voltage part including an energy source connected to a primary winding of a pulsed transformer, and a high-voltage part including a secondary winding of the pulsed transformer connected to a capacitor, the capacitor being connected to a magnetic switch, the magnetic switch being connected to a load, characterized in that a unidirectional low-impedance path for the charge of the capacitor is connected in parallel to the load, and wherein said low impedance path includes a freewheeling diode.

  • Antenna protection device
    Patent number: 6366251
    Abstract: An antenna protection device for insertion between sections of an antenna for cutting the passage of low-frequency alternating electric current. The device comprises a non-linear capacitor with capacitor plates connected to the antenna sections. The non-linear capacitor is characterized by a negative low-frequency voltage coefficient, whereby the passage of a high frequency alternating current remains essentially unaffected.
