Abstract

The low-level unregulated DC voltage provided by a fuel cell stack is connected to a boost-type DC power converter to step up the voltage applied to a given load. This output voltage tends to decrease as more current is demanded from the cell. Thus, a control scheme is required to regulate the output voltage. It is shown that linear, time varying, state feedback controllers, based on integral passive output feedback, acting on exact open loop trajectory tracking error models of a large class of power electronics devices, semi-globally stabilize the regulation error to zero.
