Abstract (en)
The invention is in the field of DC power supply and concerns building infrastructure systems, e.g. lighting devices. A surge protection circuit for a power supply interface of a DC-to-DC converter device comprises a serial circuit element connected between the DC input voltage lines configured to implement a low-pass filter, and a linear regulator circuit element including at least one transistor. The invention concerns a DC-to-DC converter device for generating a load current for an electric load, e.g. a LED current for at least one lighting module, from a DC supply voltage. The DC-to-DC converter device comprises a converter circuit configured to generate the load current and to output the load current via an output interface to the electric load, and the surge protection circuit connected between a DC grid interface for obtaining the DC supply voltage and the converter circuit.
