Design of a Nonlinear Controller For a Two-Stage DC-AC Converter For DC-Link Drive Applications

As electric machine drives are growing in complexity, controlling the dc-link voltage within their drive train has become an increasing challenge. This paper implements a nonlinear peak current mode (PCM) controller in a dc-dc converter in drive applications. Unlike conventional PCM controllers which rely on constant or linear slope that is generated by the converter’s inductor current to control ...
