TLDR
In this article, a personal care apparatus consisting of a load (LD) and a switch (SW) is coupled in series between a first and a second (2) supply terminal for receiving an alternating voltage, with a rectifying circuit (RC) for converting the alternating voltage into a direct voltage, and a safety circuit (SC) which is coupled between a third (3) and fourth (4) supply terminals for receiving the direct voltage and which comprises a capacitive sensor (CS) for the detection of the presence of a part of a human body in the proximity of theAbstract:
A personal-care apparatus comprises a load (LD) and a switch (SW), which load (LD) and which switch (SW) are coupled in series between a first (1) and a second (2) supply terminal for receiving an alternating voltage, the personal-care apparatus further comprising a rectifying circuit (RC) for converting the alternating voltage into a direct voltage, and a safety circuit (SC), which is coupled between a third (3) and a fourth (4) supply terminal for receiving the direct voltage and which comprises a capacitive sensor (CS) for the detection of the presence of a part of a human body in the proximity of the personal-care apparatus, the safety circuit being adapted to control the switch (SW) in response to said detection.read more
