VI BRICK Bus Converter Level 1 DC Behavioral Model for 48 V to 8 V, 240 W

VI BRICK Bus Converter Level 2 Transient Behavioral Model for 48 V to 8 V, 240 W

Figure 16 — This model characterizes the DC operation of the VI BRICK bus converter, including the converter transfer function and its losses. The model

enables estimates or simulations of output voltage as a function of input voltage and output load, as well as total converter power dissipation or heat gen-

eration.

Figure 17 — This model characterizes the AC operation of the VI BRICK bus converter including response to output load or input voltage transients or

steady state modulations. The model enables estimates or simulations of input and output voltages under transient conditions, including response to a

stepped load with or without external filtering elements.
