This paper addresses the important issue of efficient error correction in switching power output stages. A fundamental approach is taken, where a suite of various linear and non-linear control methods are investigated in theory and practice. Linear control systems prove to have a range of advantages compared with the investigated non-linear systems. The advantages cover simple modeling and optimization, low implementation complexity, effective error correction of all power stage generated errors and controllable performance. The theoretical benefits of non-linear control are not easily realized in hardware due to a range of inherent limitations.
