  • Device for converting a very-low-amplitude steady voltage signal into an alternating voltage signal
    Patent number: 5329440
    Abstract: This device for converting a very-low-amplitude steady voltage signal into an alternating voltage signal, of the type comprising a centre-tapped transformer (1) associated with a transistor (3,4) chopper (2), is characterised in that the transformer (1) and the transistors (3,4) are arranged in a housing (15) held at very low temperature and in which is arranged a material (20) for thermal insulation of the transistors (3,4) with respect to the rest of the housing so as to reduce temperature fluctuations and allow operation of these transistors by self-heating due to their drive current.
