Abstract :
Low-frequency components of states or outputs in PWM dc and ac converters can be characterized by differential equations called describing equations. These equations are derived by inspection of converter topology and use of switching functions and duty ratios. Their steady-state and small-signal dynamic solution shows how energy-storage elements in a converter/load system shape the frequency response of conversion functions established by the switches.
