Abstract
There is described a power supply for lamps, particularly for LED-MR16 lamps; the power supply receives an alternating voltage, particularly provided by an electronic transformer, at the input between first and second input terminals. The input alternating voltage has a high frequency component and the power supply comprises rectifier means of said input alternating voltage and at least one capacitor connected to the output of said rectifier means; the voltage at the ends of said capacitor is adapted to supply the lamp. The power supply includes a capacitive circuit arranged between the first and second terminals and adapted to be charged by the negative half-wave of the high frequency component of the input alternating voltage; the capacitive circuit adapted to discharge to the capacitor in the presence of the positive half-wave of the high frequency component of the input alternating voltage.
