An efficient DC-DC boost converter for thermoelectric energy harvesting

System uncertainties estimation based adaptive robust backstepping control for DC DC buck converter

“…= − (12) It can be noticed that and are unknown due to the uncertainty of the load resistance and the input source. In literature, since the uncertainty 1 appears in the divertive of the load voltage expression 11, which is not dependent directly on the input; thus 1 is called mismatched uncertainty, and 2 that expressed in (12) is called a matched uncertainty. The objective of this work is to design a robust controller that makes the output voltage tracks the reference voltage in the presence of mismatched and matched uncertainties.…”

“…This nonlinearity and uncertainty of the DC-DC converter model make the control of the DC-DC converter as a big challenge. Hence, many control schemes had been presented to control the DC-DC converter [9][10][11][12][13]. Soft computing algorthims had been applied sucesfuly in tuninig controller ganis for many complicated systems [14][15][16][17][18].…”

An Improved Particle Swarm Optimization Algorithm for Maximum Power Point Tracking Of Photovoltaic Cells in Normal and Under Partial Shading Conditions.(Dept.E)

“…The boost converter is essential to the photovoltaic generation process because the boost converter tracks the MPP created by the PV panel that allows the adjustment of the voltage provided by the panel by acting on its duty cycle d [32].…”

A 0.4 V, 19 pW subthreshold voltage reference generator using separate line sensitivity and temperature coefficient correction stages

“…Voltage reference generators are one of the principle blocks used in many analog/mixed signal circuits such as data converters [1], sensors [2], and regulators [3]. With the development of applications such as the IoT and energy harvesting circuits in which power consumption is important [4], sub-threshold voltage references consuming picowatt power have attained more attention. Voltage reference generators with output Independent of Temperature (IT) can be designed by combining circuits which produce output voltage or currents Proportional To Absolute Temperature (PTAT) and Complementary To Absolute Temperature (CTAT) [5,6].…”
