Abstract
The invention describes a surge-protection arrangement () for an electronic device () comprising a heat-dissipating load () thermally connected to a heat sink () of the load (), which surge protection arrangement () comprises at least one high impedance arrangement (Z, Z, Z) connected in series with the load (); at least one low impedance arrangement (Z, Z, Z) connected in parallel with the load (); and a ground connection (FE) arranged to electrically connect the heat sink () and a low impedance arrangement (Z, Z, Z); wherein the high-impedance arrangement (Z, Z, Z) is realized to discourage a common-mode surge current (Is) from entering the load (), and the low-impedance arrangement (Z, Z, Z) is realized to encourage a common-mode surge current (Is) to bypass the load () into a ground connection (FE). The invention further describes an electronic device () comprising a load () with a number of heat-dissipating components () thermally connected to a heat sink () of the load (); a driver () realized to drive the load (); and such a surge protection arrangement (). The invention also describes a driver () realized to drive an LED lighting circuit () and comprising such a surge protection arrangement (); and a method of providing protection against a common-mode surge current (Is) through an electronic device () comprising a heat-dissipating load () thermally connected to a heat sink () of the load ().
