In this paper we present the top-down fabrication of gate-all-around (GAA) and body-tied X-gate devices by a combination of etching and oxidation steps resulting in a local silicon-on-insulator structure. The GAA has advantages in terms of enhanced current drive, whereas the body-strapped structures allow for active leakage control and in some cases impact ionization devices. We demonstrate an ...

This paper describes a discrete adaptive state feedback controller used to load current control in terms of variable DC voltage of inverter. Controller was designed by using linear quadratic optimization method. Adaptive LQR was used because of non-stationarity of the control system caused by Voltage Matching Circuit VMC. Gain values of the adaptive controller were approximated by using an arti...

The main objective of this paper is a space vector pulse width amplitude modulation (SVPWAM) method for a buck–boost voltage/current source inverter. For a voltage source inverter, the switching loss is reduced by 87%, compared to a conventional sinusoidal pulse width modulation (SPWM) method. For a current source inverter, the switching loss is reduced by 60%. In both cases, the power density ...
