| 摘要 |
The invention proposes an electronic adaptor circuit for obtaining voltage for an electronic component or a component assembly. The circuit is characterized in that between input terminals (5, 6) and output terminals (7, 8) there are connected elements for transmission of variable voltage with a wide range of voltages, which comprise a low-loss current limiter (2) that limits current (i) at the output terminals (7, 8) to a predetermined value, whereby said output terminals (7, 8) are connected for transmission of voltage signals to a control input of the further connected electronic component or the component assembly and the current limiter (2) contains series-connected transistors (30, 31), whereby the second transistor (31) base-collector junction is parallel-connected to the first transistor (30) emitter-base junction.
