High Reliability and Performance PWM Inverter for Standalone Microgrids
(Institute Of Electrical And Electronics Engineers, 2013-02)
In this paper a high reliability and performance single-phase PWM inverter for standalone microgrids is presented. To obtain the before mentioned characteristics this work propose, two different controller structures and ...
Sinusoidal PWM Techniques Comparison for the Quasi-Y-Source Inverter
(2021-10-01)
Impedance network inverters (INIs) have emerged as an alternative to improve traditional inverters, allowing their operation as a buck-boost-type converter, through the utilization of the “shoot-through” conduction state, ...
Centralized Control Center Implementation for Synergistic Operation of Distributed Multifunctional Single-Phase Grid-Tie Inverters in a Microgrid
(2018-10-01)
This study discusses a centralized and coordinated control of distributed multifunctional inverters connected to an electric grid. The multifunctional operation is based on the conservative power theory, which makes it ...
An evidence of mixed-valence electron transfer in the inverted Marcus region
(1998)
The rates electron transfer ket for the mixed-valence complexes [Cd(dppe)Fe-CN-MLn]+2, MLn = Cp(dppe)Fe, Mn(CO)2dppmP(OPh)3 and other cyanide bridged complexes were estimated from the intervalence transition parameters. ...
Effect of the addition of invert sugar on the production of cephalosporin C in a fed-batch bioreactor
(Brazilian Society of Chemical Engineering, 1998-12-01)
Cephalosporin C, a b -lactam antibiotic, is the starting molecule for industrial production of semi-synthetic cephalosporins. The bioprocess for its production is carried out in batch stirred and aerated tank reactors ...
Micro-inverter for integrated grid-tie photovoltaic module using resonant controller
(Wiley-Blackwell, 2014-05-01)
Two-stage isolated converters for photovoltaic (PV) applications commonly employ a high-frequency transformer (HFT) on the DC-DC side, submitting the DC-AC inverter switches to high voltages and forcing the use of ...
Ideal switched-model dynamic stability conditions for semi-quasi-Z-source inverters
(Pergamon-Elsevier Science Ltd, 2016-01)
The ideal switched model of the recently introduced semi-quasi-Z-source inverter is a practical example of a switched system where each subsystem is neither asymptotically stable nor detectable from the output, yet asymptotic ...
