Abstract:
A method of forming a power module comprising the steps of:forming a semiconductor substrate;forming spaced apart power transistor circuits in the substrate, each having respective anode and cathode portions;attaching flexible cathode straps to the cathode portions;attaching flexible anode straps to the anode portions;enclosing the substrate within a power module housing and extending the anode and cathode straps out of the power module housing spaced from each other;folding at least two anode straps and cathode straps over at least a portion of the power module housing to overlap respective straps to form phase straps; andfolding the remaining cathode and anode straps over at least a portion of the power module housing such that respective anode and cathode straps overlap each other and in overlapping engagement to each other thereby lowering inductance and reducing voltage overshoot at turn off.
