AN ELECTRIC CIRCUIT FOR CONTROLLING THE SUPPLY OF ELETRIC CURRENT TO A LOAD COMPRISING A RECTIFIER BRIDGE ACROSS ONE DIAGONAL OF WHICH IS ARRANGED TO BE SUPPLIED AN ALTERNATING CURRENT SIGNAL FROM A SOURCE, THE LOAD BEING ARRANGED TO BE CONNECTED IN THE PATH BETWEEN ONE END OF SAID DIAGONAL AND THE SOURCE, GATE MEANS CONNECTED WITH SAID RECTIFIER BRIDGE SO THAT WHEN SAID GATE MEANS HAS A GIVEN CONDITION AN ALTERNATING CURRENT VOLTAGE IS SUPPLIED FROM THE SOURCE TO THE LOAD, AND MEANS TO DRIVE FROM THE SOURCE A SIGNAL HAVING A FREQUENCY NOT GREATER THAN TWICE THE FREQUENCY OF THE SIGNAL SUPPLIED TO THE RECTIFIER BRIDGE, EACH CYCLE OF THIS DERIVED SIGNAL BEING ARRANGED TO TRIGGER A TWO-CONDITION MONOSTABLE CIRCUIT INTO ITS UNSTABLE CONDITION AND THE GATE MEANS BEING CONTROLLED SO THAT IT HAS SAID GIVEN CONDITION WHILE THE MONOSTABLE CIRCUIT IS IN ONE ONLY OF ITS CONDITIONS, THE MONOSTABLE CIRCUIT HAVING PROVISION TO VARY THE DURATION OF INTERVALS DURING WHICH IT REMAINS IN ITS UNSTABLE CONDITION SUBSEQUENT TO BEING TRIGGERED INTO THIS UNSTABLE CONDITION, THE ARRANGEMENT BEING SUCH THAT VARIATION OF THE DURATION OF THE INTERVALS DURING WHICH THE MONOSTABLE CIRCUIT REMAINS IN ITS UNSTABLE CONDITION RESULTS IN CONTROL OF THE SUPPLY OF ELECTRIC CURRENT TO THE LOAD.
