  • Electronic temperature sensor for measuring the junction temperature of an electronic power switch during operation, and method for measuring the temperature of the junction by this electronic sensor
    Patent number: 9442023
    Abstract: An electronic temperature sensor for measuring the junction temperature of an electronic power switch (4) of a static converter (8) includes an injection source of a calibrated measurement current (20) and a differential voltage measurement amplifier (76; 276). The electronic temperature sensor includes a first series connection (26) element and a second series connection (28) connected respectively to the inlet terminals (78, 80) of the differential voltage amplifier (76; 276). The first and second series connection elements (26, 28; 224, 226) are configured to protect the amplifier against a high voltage, have essentially identical electrical characteristics and are included in the set formed by resistances and high-voltage (HV) rapid diodes.
