An active damping technique for a current source inverter employing a virtual negative inductance
(2010 , Conference Paper)
A grid connected CSI requires a CL filter stage. In this work, the isolation transformer leakage inductance constitutes this filter inductance. This CL filter is lightly damped for efficiency constraints. Hence, it is ...
Assessment of sensorless Kalman filter-based dual-loop control strategies for grid-connected VSIs with LCL filters
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper illustrates the assessment between the multiloop control strategies that aim to damp the resonance hazard of LCL-filters and expanding the available stability margins. The establishment of the multiloop control ...
An active-damped LLCL filter for grid-tied three-phase voltage source inverter with PR current control
(
Institution of Engineering and Technology
, 2016 , Conference Paper)
For the grid connection of voltage source inverters (VSIs), the power passive filters are a standard solution for grid-current harmonic attenuation. However, these types of filters may cause resonance between the inverter ...
An active damping approach for PR-based current control of grid-tied VSI with LCL filter
(
Institution of Engineering and Technology
, 2016 , Conference Paper)
The use of the Voltage Source Inverter (VSI) in Distributed Power Generation Systems (DPGS) and their connection to the utility network requires low pass filters which are typically used for grid current harmonic suppression. ...
New switching technique for quasi-Z-source resonant converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
© 2018 IEEE. The Quasi-Z-Source (QZS) inverters are the promising topology for the renewable integration with the grid. QZSI achieves the MPPT during the shoot through state, without additional DC-DC converter, and ...
