Points of this article
・? Derive the transfer function of the part that generates the PWM output from the output of the error amplifier and the slope wave.
We will now consider the transfer function of the slope. The following figure is Figure 2 used in “Basic Concepts of Transfer Function and Derivation.” From this chapter, we will discuss the PWM and driver part G2(S), which follows the error amplifier part G1(S) up to the previous chapter.
Typical PWM control includes voltage mode and current mode. This chapter describes the following.

This handbook explains how to derive transfer functions, starting with basic equations and an RC low-pass circuit. It covers gain and phase, functional block decomposition of DC-DC converters, voltage- and current-mode control, and derivation procedures using state-space averaging. It also summarizes subharmonic oscillation and slope compensation, with links to TechWeb articles for detailed derivations.
