(
Springer Verlag
, 2018 , Conference Paper)
This paper presents different controlling techniques of the converter used for the solar photovoltaic water pumping system (SPVWPS) driven by permanent magnet DC (PMDC) motor. The direct-coupled PMDC motor-driven solar ...
Overvoltage and raised fault current issues in active distribution networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
© 2018 IEEE. In this paper, two main challenges, namely over voltage and raised fault current levels, in active distribution networks, are addressed. Voltage profile and raised fault current in normal and fault conditions, ...
Model-predictive control for common-mode voltage reduction and third-harmonic current injection techniques with five-phase inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
This paper employs a Model Predictive Control (MPC) technique to reduce the Common-Mode-Voltage (CMV) in five-phase inverters when third harmonic current injection is applied. According to the inverter space vector model, ...
Harmonics minimization in 3-level inverter waveform and its FPGA realization
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The multilevel inverter (MLI) is more preferred for medium voltage high power application as it produces better quality voltage waveforms (stepped in nature) with reduced harmonic distortion (less THD), operates at less ...
Discrete Input Signaling for Secure MISO VLC Systems with Randomly Located Eavesdroppers
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
We study in this paper the secrecy performance of the multiple-input single-output (MISO) visible light communication (VLC) channel in the presence of randomly located eavesdroppers. We consider a system model comprising ...
High-gain DC-DC converters for high-power PV applications: Performance assessment
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Conventional non-isolated DC-DC converters provide limited practical gains at high duty cycles due to their parasitic losses. Such trend is not suitable for renewables grid integration due to the high required gain, while ...
