Electronic half-bridge rectifier module unit for IC engine starter/AC generator circuit, has semiconducting part with surface attached to multiple lower circuit boards, common connection coupled to each lower board, and upper circuit board

摘要

The unit has a thermally conducting base part (4), a number of lower circuit boards (6,8) arranged adjacent to each other in the base part along a common plane, at least one semiconducting component with a first surface attached to a number of different circuit boards, a common connection (14) with a flat section coupled to each lower circuit board and an upper circuit board (42) in electrical contact with the lower boards. The upper board includes a connection device (46) giving external access to drive signals for the semiconducting component.
