摘要:
Electric driver comprising: a carrier (1) in the form for instance of a PCB; a first electrical component (10) and a second electrical component (20), wherein the first electrical component (10) and the second electrical component (20) are provided on the carrier (1); and a heat insulation structure (2), wherein the second electrical component (20) comprises a first heat insulator (21) surrounding the second electrical component (20) and a second heat insulator (22) surrounding the first heat insulator (21), wherein a gap (3) is provided between the first heat insulator (21) and a second heat insulator (22). The proposed electric driver improves the lifetime of the second electrical component (20) as the heat insulation structure (2) provides a thermal insulation to said second electrical component (20) with respect to the first electrical component (10). This can be particularly advantageous when the second electrical component (20) consists in an electrolytic capacitor, which is particularly sensitive to the temperature.
