A Multilevel Voltage Source Inverter for Two-Phase AC Motor Drive Systems
Guerreiro, M.; Fernao Pires, V.; Foito, D.; Cordeiro, A. (2011-09-10)
This paper presents and studies a multilevel converter with two DC voltage sources and three H Bridges. The inverter modulates two independent single-phase voltages using a four wires output. The design of the inverter allows five levels to the modulated voltages that feed an asymmetrical two windings phase induction motor. The classical SPWM technique was used to modulate the multilevel power inverter switches; the frequency of the carrier (a triangular wave) was varied and total harmonic distortion (THD) ...
A CMOS switched-capacitor interface circuit for an integrated accelerometer
Külah, Haluk; Najafi, K (2000-01-01)
This paper presents a CMOS interface electronics for monolithic micromachined capacitive accelerometer systems. The interface electronics is a fully differential switched-capacitor charge integrator with its internal clock generator and sensor feedback circuit for closed-loop operation. The circuit is designed for open-loop and closed-loop operations, and provides both digital and differential analog outputs. One of the main advantages of this chip is that it can be monolithically integrated with the sensor...

A current source converter based statcom for reactive power compensation at low voltage
Biçer, Nazan; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2010)
This research work is devoted to the analysis, design and development of the Current-Source Converter (CSC) based distribution-type Static Synchronous Compensator (D-STATCOM) for low-voltage applications in reactive-power control in order to achieve i) faster transient response in reactive-power control, ii) lower current harmonic distortion, iii) lower power losses and iv) minimum storage elements in comparison with conventional solutions. The developed CSC-D-STATCOM includes a low-pass input filter and a ...
A Parabolic Band Hysteresis Current Controller for Doubly Fed Induction Generators
Hamadi, Emad; Mortazavi, S. S. (2011-09-10)
A parabolic band hysteresis current controller (PBHCC) for DFIG is proposed in this paper to control the switching frequency variations in rotor side converter (RSC). A generalized online technique is used to determine the set of unique parabolic boundary for any operation speed. The PIHICC then utilized to regulate the current in RSC. In contrast to PI controller, PBHCC shows a very good transient behaviour. Beside that, the steady state performance is improved by reducing the switching frequency considera...
