Figure 21 — This model characterizes the DC operation of the 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 generation.

Figure 22 — This model characterizes the AC operation of the 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.
