1. A power module comprising:
a molded package;
three power terminals protruding from a first side of the molded package, wherein these power terminals include a positive DC terminal, a neutral terminal and a negative DC terminal; and
a phase output power terminal protruding from a second side of the molded package, wherein the power module is a three-level power module comprising a plurality of control pins protruding from the second side of the molded package and a plurality of metallisation areas including:
a) a neutral terminal metallisation area is electrically connected to the neutral terminal;
b) a phase output power terminal metallisation area is electrically connected to the phase output power terminal, and
c) the neutral terminal and the phase output power terminal metallisation areas are aligned with each other along a common axis (X) extending from the first side to the second side, wherein the phase output power terminal metallization area has an elongated shape extending parallel to the common axis (X).
