The present invention aims to provide a control method much simpler and less expensive from a single or three phase dimmer for supplying resistive loads, using a control syncopated by synchronized isolated alternation of the supply voltage switching circuits said loads, said method being characterized in that it generates a control pulse signal whose frequency is proportional to the mean power supplied to the load of a phase, said control signal causing the switching of a single alternation of the supply voltage on said phase from the zero crossing, or on the rising or falling edge of said supply voltage.
