Abstract—In this paper, modeling of a three-phase Active
Power Filter (APF) considering hybrid dynamics is investigated.
A shunt active filter is considered to compensate for the current
disturbances from the utility load. Power electronic circuits
using APFs are considered as hybrid systems, and the concepts
and theories of switched linear systems are introduced to model
converter control systems. First, a three-phase converter system
is equivalent to a switch linear system (ESLS) based on space
vector pulse-width modulator (SVPWM) theory. Then, an ESLS
is further transformed into a linear equivalent switch linear
system by linearization. Finally, an energy-to-energy (EE)
controller is designed.
Index Terms—Active power filter, switched linear system,
pulse width modulated.
