Abstract

A voltage regulator circuit having two terminals adapted to be connected to an AC voltage generator (30) and respectively to a load (39) to be supplied with a predetermined effective voltage. The circuit comprises a bidirectional electronic switch (33) and control means for closing and opening the switch during a positive half wave of generator voltage in a first direction and for closing and opening the switch during a negative half wave in a second direction. The bidirectional switch comprises two one directional electronic switches (34,35) in series, each of them has in parallel one of two opposite diodes 8 and 9.
