Case Study 3: DC-DC Power Converter
Case Study 3 illustrates how VHDL-AMS can be used for the detailed design of a 42V to 4.8V DC-DC switching power supply. We briefly introduce switched-mode power supply theory, and then perform a detailed design of a simple step-down (buck) converter using SystemVision. We discuss averaging techniques that facilitate analysis of the closed-loop system and run additional simulations to perform system-level design tradeoffs.
