Voltage Regulation of a Boost Converter in Discontinuous Conduction Mode: A Simple Robust Adaptive Feedback Controller

Abstract : Ideal switches in power converters are typically implemented using unidirectional semiconductor devices that may lead to a new operation mode generically called discontinuous conduction mode (DCM). The DCM arises when the ripple, that is, sustained oscillations of small amplitude, is large enough to cause the polarity of the signal (current or voltage) applied to the switch to reverse. Due to the presence of diodes, switches are assumed to operate unidirectionally, but in DCM this unidirectionality assumption is violated. In classicalconverter topologies, DCM appears very frequently in low load operating modes. More interestingly, to achieve high performance some new converters are purposely designed to operate all the time in DCM [1].
