Abstract:
A method for complementing the AC mains supply voltage, particularly for use with resistive loads, comprising the steps of:process the AC voltage output from an AC source towards a resistive load so as to obtain a rectified but still sinusoidal voltage, and preventing a reverse flow of the resulting processed voltage towards said AC voltage power source;storing said rectified AC voltage in at least one capacitive means arranged ahead of said resistive load;complementing, during discharge of said at least one capacitive means towards said resistive load, said AC supply voltage until a desired voltage increase with respect to the actual value of said voltage supply is reached, said voltage increase being obtained by choosing the values of said one or more capacitive means by multiplying the required additional watts, determined by measuring the actual power consumed by the resistive load and subtracting it from the nominal power of the load, by a constant factor derived from the relationships between the capacitance values and the supply voltage values, said actual power being the power consumed by the resistive load powered by the AC voltage supply, said nominal power being the power that the resistive load consumes when the supply voltage supplied to said load has an optimum and predetermined value for the load.
