Abstract:
1. An AC voltage controller, comprising: two AC voltage terminals; two transistors having source terminals and connected between said two AC voltage terminals in series with a load, said two transistors connected in series such that said source terminals are connected to one another; a signal generator for generating a switching signal for simultaneously actuating both of said two transistors; a buffer connected downstream of said signal generator and set by said signal generator to simultaneously actuate both of said two transistors; a circuit, selected from the group consisting of an actuation circuit and a driver circuit, connected downstream of said buffer, for actuating said two transistors in accordance with a set state of said buffer; and a current-limiting circuit for limiting or switching off a current through said two transistors in a case of an excessively large current through the load.
