  • Switchable inductor for strong currents
    Patent number: 5412310
    Abstract: Switchable inductors for strong currents are used especially in antenna tuning circuits. The value of the inductance between the terminals of the primary winding of an air-core static transformer is different depending on whether the secondary winding of the transformer is placed in an open circuit or in a short circuit by switching means formed by power semiconductor elements. Application in particular to antenna coupling circuits for VLF stations working by frequency hop transmission with highly selective antennas.

  • Charged-coupled device for high-power transmitters
    Patent number: 5218317
    Abstract: A transmitter which includes N amplifiers connected together by a common signal input and which output to a common load. The transmitter also includes N identical series LC circuits, each connected between an amplifier output and the common load, with the common points between each inductance and capacitance connected together. The extremely modular nature of the device makes the transmitter easy to reconfigure if one of the amplifiers fails.
