Active power decoupling methods are becoming an attractive
alternative to networks of passive elements in filtering
the power ripple in single phase rectifiers, as they offer better
power density. In this article we develop a variable structure
control algorithm for the control of active power decoupling.
In the process the main design challenges are identified,
and a new solution method for the design problem is developed
based on the application of control actions across multiple
time-scales. The resulting algorithm operates independently
from the controller of the rectifier and stabilized the dc-link
voltage during power transients.
