This paper presents a CMOS bandgap reference that employs a curvature correction technique for compensating the nonlinear voltage temperature dependence of a diode connected BJT. The proposed circuit cancels the first and the second order terms in the VBE(T ) expansion by using the current of an autopolarized Widlar source and a small correction current generated by a MOSFET biased in weak inve...

A source-to-target computer model for an induction linac driver for heavy ion fusion has been developed and used to define a reference case driver that meets the requirements of one current target design. Key features of the modelare discussed, and the design parameters of the reference case design are described. Examples of the systems analyses leading to the point design are given, and direct...

The Shunt active power filters are used in power systems for the compensation of harmonic currents generated for non linear loads. A reference current estimation method for control of SAPF using a digital filter based synchronous reference frame theory is presented. To extract the fundamental component of source current, the synchronous reference frame (SRF) theory is suitable because of its ea...

Most of the pollution issues created in power systems are due to the non-linear characteristics and fast switching of power electronic equipment. Power quality issues are becoming stronger because sensitive equipment will be more sensitive for market competition reasons, equipment will continue polluting the system more and more due to cost increase caused by the built-in compensation and somet...
