13.4.2 Model
The dynamic characteristic of the triode vacuum tube is modeled by its DC characteristic with
three capacitances (Cgk, Cpk, and Cgp) which are associated interelectrodes.

13.5 Boost Converter
This component is an averaging circuit model that models the averaging behavior of a step-up
DC-to-DC switching converter. It is based on a unified behavioral model topology. The
topology models both small-signal and large-signal characteristics of this converter power
stage. The model can be used to simulate DC, AC and large-signal transient responses of
switched-mode power supplies operating in both the continuous and discontinuous inductor
current conduction modes (CCM and DCM, respectively).
