Claim 12:
13. The hybrid double-sided power switch module of claim 12, wherein said at least first and second switch dies include a plurality of switch dies S1, S2, S3, S4, S5, S6, S7, S8,
said switch dies S1 and S2 forming a first phase-leg having a first capacitor coupled between said switch dies S1 and S2 and a first MFC forming a first AC1 bus-bar,
said switch dies S3 and S4 forming a second phase-leg having a second capacitor coupled between said switch dies S3 and S4 and a second MFC forming of a second AC2 bus-bar,
said switch dies S5 and S6 forming a third phase-leg having a third capacitor coupled between said switch dies S5 and S6 and a third MFC forming a third AC3 bus-bar, and
said switch dies S7 and S8 forming a fourth phase-leg having a fourth capacitor coupled between said switch dies S7 and S8 and a fourth MFC forming of a fourth AC4 bus-bar,
a common MFC in a form of an AC bus-bar connected to said AC1, AC2, AC3 and AC4, bus-bars, wherein said first, second, third and fourth phase-legs are connected in parallel between respective MFCs in a form of DC1+ and DC1− bus-bars,
wherein each of said first, second, third and fourth capacitors is secured to said DC1− and DC1+ bus-bars in each of said phase-legs,
wherein said switch dies in each phase-leg are disposed at opposite first and third sides of said first and second PCBs, respectively, and
wherein said switch dies on said first side and second side of said first and second PCBs, respectively, are arranged in a single row of switch dies.
