Abstract:
1. A power module comprising: a) a first module block defining a first synchronous rectifier and including a first synchronous rectifier switch having a first power FET and connected in parallel with a first diode; b) a second module block including a second power FET connected in parallel with a second diode; c) a third module block including a third power FET connected in parallel with a third diode, wherein the second and third module blocks are positioned between first and second terminal interfaces of the power module, and wherein two serially connected diodes are utilized on the first terminal interface side of the power module in parallel with the serially connected second and third module blocks; and d) a fourth module block defining a second synchronous rectifier and including a second synchronous rectifier switch having a fourth power FET and connected in parallel with a fourth diode; wherein each synchronous rectifier comprises a silicon carbide (SiC) power MOSFET connected in parallel with a power diode, the power diode being a silicon carbide (SiC) Shottky diode.
