Beschreibung
Zusammenfassung:	The invention refers to a power unit (10) of a passenger transporting device, comprising a control circuit (12) and a power circuit (14), whereby the power circuit (14) comprises several discrete surface mounted power semiconductors (40a, 40b, 40c) which are located on a metal substrate printed circuit board (MSPCB) (30). The MSPCB (30) has a metal substrate layer (34) covered by a dielectric layer (36) on which a circuit layer (38) with the power semiconductors (40a, 40b, 40c) is arranged. The control circuit (12) comprises a separate printed circuit board (PCB) (20) consisting of a circuit layer (24) with control circuit components (16, 18) located on a polymer- or glass substrate (22).
