Abstract

A current switch control system includes a first controllable switch, a first current switching controller, a second controllable switch, a second current switching controller, and a reference value controller. Each current switching controller generates a pulse width modulated switching signal to change the state of one of the respective controllable switches based on a current reference value and a current measured value corresponding to current flow through the respective controllable switch. The reference value controller changes the current reference values used by the current switching controllers based on the pulse width modulated switching signals for the controllable switches.
