摘要：A circuit arrangement includes a lamp filament (1) as a load and a resistor (2) in ries with the filament. For detecting the current through the load, the source of a
MOSFET (6) is connected with the end of the resistor remote from the filament, the drain of the MOSFET being connected with the other end of the resistor via the primary
winding of a step-up transformer (7) and a further resistor (8), a diode (9) being connected between the source and the drain of the MOSFET. If the MOSFET is turned on by an appropriate voltage at an input (11) connected to its gate, the voltage across the condary winding of the transformer is substantially proportional to the value of the current through the filament.
