Alternating current positioner

摘要

The adjuster has two transistors (4, 5) e.g. bipolar transistors, positioned between alternating current voltage terminals (7, 8) in series with a load (6) and connected in series with each other such that source terminals are connected to one another. A signal generator (1) generates a switching signal for actuating the transistors, and a buffer (2) is connected downstream of the generator and set by the generator to actuate the transistors. A current-limiting circuit limits or switches off the current through the transistors when excess current passes through the load.
