Part 1: New Fast Switching Power Semiconductors in Innovative SMT Packages for 10 kW 3-Phase Vienna Rectifier

This 3-phase Vienna Rectifier Reference Design is focused to effective application of new Power Switching Components in Innovative SMT packages. The new Si / SiC MOSFETs and GaN HEMTs allow the switching frequencies increase up to few 100kHz and give space to reduce the magnetic components size, cost, increase power density, etc. Opposite of these benefits stay requirements for fast Current Sensing, Over-Current protections, DSPs with higher computing power, fast ADCs, DACs, optimal PCB layout and innovative heat transfer from SMT power devices to heatsink. As always, we should do a compromise and try to found an optimum for whole Power Supply concept.
