摘要： An AC voltage controller has two transistors which can be positioned between two AC voltage terminals in series with a load. The two transistors are connected in series in such a way that their respective source terminals are connected to one another. The AC voltage controller also contains a signal generator for generating a switching signal for actuating the two transistors, a buffer which is connected downstream of the signal generator and which is set by the signal generator in order to actuate the two transistors. An actuation circuit or driver circuit is connected downstream of the buffer, for the purpose of actuating the two transistors in accordance with the set state of the buffer. A current-limiting circuit is provided for limiting or switching off the current through the two transistors in the case of an excessively large current through the load.

摘要： A voltage regulator for regulation both of AC and of DC voltages, is provided in a regulator module (30) which uses a repetitive switching signal (32) to control a switch (36) allowing current to be supplied to a reservoir capacitor (42) by supply from an unregulated rail (18). The module contains a dual inductor (44, 46, 48) having first (44) and second (46) identical windings and a common core. A current pass capacitor (43) is also provided. When the switch (36) is closed, the first winding (44) delivers current to the reservoir capacitor. When the switch (36) is open, both the second (44) and the first (46) windings deliver current to the reservoir capacitor (42). The apparatus can support balanced operation, where pairs of switches are operated alternately and oppositely. The switching signal (32) can be suitably voltage restored to provide a signal suitable to control and operates switches (36). Different configurations of transistor switches (36) and diodes (38) are shown.
