| 摘要 |
The invention relates to an electronic switch (1) for switching a load (7), having a current path (3) which runs between an operating voltage connection (5) and a load connection (6a) and to which a power transistor (2) and a current sensor (4) sensing the load current (IL) are connected, and having a control or regulating device (8, 9) which controls the power transistor (2) on the basis of the load current (IL), wherein the control or regulating device (8, 9) is connected to the secondary circuit (15) of a converter circuit (12) having a transformer (13), the primary circuit (14) of which is connected to the operating voltage connection (5) via a controlled switch arrangement (19, 20). |
