Abstract:
1. A control circuit for reducing Total Harmonic Distortion (THD) in the power supply to an electric load, comprising: a. An input stage for receiving a network voltage and providing a corresponding rectified sinusoidal output supply voltage; b. An output stage associated with said input stage for providing power supply to an electric load; c. A control module configured to control the power factor and the harmonic distortion (THD) of the energy obtained from said network voltage, by regulating a pulse current that acts upon the power supply absorbed by said output stage; d. A regulating module configured for: wherein said control module is configured to modify the pulse current according to said regulating signal; wherein said control module comprises a processing unit, which is designed to receive an input signal representative of said supply voltage, to receive as an input, through a first reading branch, a current sense signal representative of said pulse current and to control said pulse current according to said input signal and said current sense signal; wherein said regulating module is configured to:
