Abstract

A circuit for the sinusoidal regulation of the electrical power supplied to a load includes an input interface to receive an electrical power supply from a power supply unit and an output interface to supply a predetermined electrical power to a load; the circuit further includes a plurality of capacitive elements, a plurality of thermistor regulator elements and a plurality of commutators, each associated to a respective capacitive element. Each commutator is able to be driven between a first operative condition in which it closes a connection between the load, the respective capacitive element and the power supply unit, and a second operative condition in which it does not close such connection; a control block drives the commutators between their first and second operative condition and thus regulates the power supplied to the load, defining the capacitive reactance interposed between the power supply unit and the load.
