Real Time Digital Feedback Control for VFD fed by cascaded multi-cell inverter
(
IEEE
, 2010 , Conference Paper)
Multi-cell inverter include an array of single-phase inverters capable of handling higher voltage ratings with lower rating power electronics devices. In this paper, a Real Time Digital Feedback Controller (RTDFBC) combined ...
A new PLL method for resolvers
(
IEEE
, 2010 , Conference Paper)
This paper describes a novel implementation of the classical PLL closed loop method without using VCO, DAC, counter and look-up tables. The proposed method makes use of the excitation signal of the resolver to estimate the ...
Space vector pulse width modulation techniques for a five-phase impedeance source and quazi impedeance source inverters
(
IEEE
, 2015 , Conference Paper)
Impedance source inverter (ZSI) and its variant quasi impedance source inverter (qZSI) are single stage inverters that transform dc to ac and boost the source voltage at the same time. These topologies have attracted great ...
Performance enhancement of cascaded qZS-HB based renewable energy system using Model Predictive Control
(
Elsevier Ltd
, 2017 , Article)
This paper presents a multi-objective Model Predictive Control (MPC) for a grid connected 2-cell 5-level quasi Z-Source (qZS) Cascaded H-Bridge (CHB) inverter. The main contribution of the proposed control approach is the ...
Review and simulation of leakage current in transformerless microinverters for PV applications
(
Elsevier
, 2017 , Article Review)
Designing microinverters without transformers enhances system efficiency and power density and reduces cost. However, the transformer removal results in loss of galvanic isolation that leads to leakage current circulation. ...
A new tracking technique for mechanical angle measurement
(
Elsevier
, 2014 , Article)
Resolvers and other types of sine/cosine encoders are used for measurement of mechanical angles. These devices produce quadrature signals in the form of sine and cosine of the unknown angle, and require converters to extract ...
Deadbeat control with multi-sampling compensation for medium-voltage motor drives by cascaded multi-cell inverter using FPGA based hardware controller
(
IEEE
, 2011 , Conference Paper)
Multi-cell inverter include an array of single-phase inverters capable of handling higher voltage ratings with lower rating power electronics devices. In this paper, a deadbeat control combined with a multi-sampling ...
