The penetration of dc distributed power systems is increasing rapidly in electric power grids
and other isolated systems to cater demand for cheap, clean, high quality, and uninterrupted …

This paper provides a comprehensive review of the major concepts associated with the
μgrid, such as constant power load (CPL), incremental negative resistance or impedance …

Microgrid, because of its advantages over conventional utility grids, is a prudent approach to
implement renewable resource-based electricity generation. Despite its advantages …

The negative impedance characteristic of the constant power loads (CPLs) causes instability
in dc/dc converters in the dc microgrids (MGs). To improve the stability of the dc/dc converter …

The cascade connection of two dc–dc switching converters for constant power supply is
studied. The source converter is of boost type while the load converter is of buck type. The …

Multi-converter systems used in DC microgrid feed supply constant power loads (CPL) as
well as classical electrical loads. CPL has a non-linear load nature because of the negative …

This article presents a nonlinear control based on pulsewidth modulation (PWM) and an
estimation mechanism of the output power to regulate the output voltage of a boost converter …

This paper proposes a digital sliding-mode controller for a DC-DC boost converter under
constant power-loading conditions. The controller has been designed in two steps: the first …

DC/DC converter's when feeding the constant power loads (CPLs) are sensitive to the
instabilities due to the induced negative impedance characteristics. An efficient control …

The unstable ON and OFF state trajectories of a boost converter supplying a constant power
load (CPL) are appropriately combined using sliding-mode control (SMC) with a suitable …
