VIRTUAL PROTOTYPES FOR LAYOUT OPTIMIZATION
Towards Digital Twins of Power Electronic Switching Cells
Layout optimization of power electronic switching cells is important for the design of high-efficiency fast-switching power converters. Using the developed virtual prototype, the layout design is optimized to achieve lower switching losses.
This whitepaper demonstrates:
- A state-of-the-art electromagnetic tool and Spice-based device models for virtual prototyping of Power Electronic Switching Cell layouts
- The comparison between a 2-D FEM device model and Spice-based behavioral models - pointing to the necessity for standardization of Spice compact models
- A virtual prototype of Power Electronic Switching Cell layout used to re-design the PCB layout for lower switching losses
- For fast switching devices, not only parasitic layout inductances but also PCB parasitic capacitances have to be minimized!
