The interest in DC-DC switched #power_converters has increased due to the many DC electrical energy applications from #renewable_energy_sources like fuel-cell stacks, photovoltaic arrays, or wind power. In this paper, a discussion of the steady state and dynamic behavior is given for the three basic converters, i.e. buck, boost and buck-boost and introduces a practical methodology for output voltage regulation for the three basic switch-mode converters. The scheme feds back the inductor current to implement an inner #control_loop using a high-gain compensator and a low-pass filter. Furthermore, a well-defined and straightforward procedure for the selection of the controller parameters is given, which ensures system stability and output voltage regulation.
