Single feedback regulation of the AC voltage for high-power inverters under stand-alone operation
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
Energy-storage inverters under stand-alone operation must control the output voltage. However, existing methods for instantaneous voltage regulation are not suitable for high-power inverters due to their limited sampling ...
Sensorless active damping strategy for parallel interleaved voltage source power converters with LCL filter
(IEEE, 2017)
info:eu-repo/semantics/conferenceObject,
Grid-connected pulse-width modulation converters with LCL filters are widely extended as an interface for renewable energy generating systems. Those filters arise stability issues due to the filter resonance, which, must ...
Multisampled-capacitor-voltage active damping for parallel interleaved grid connected voltage source converters with LCL filter
(IEEE, 2017)
info:eu-repo/semantics/conferenceObject,
Parallel interleaved converters for high power renewable energy systems present stability issues at the LCL resonance frequency. A multisampled measurement and filtering strategy is proposed to stabilize the system based ...
On the limits of the capacitor-voltage active damping for grid-connected power converters with LCL filter
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Active damping strategies are widely extended to avoid stability issues at the LCL filter resonant poles in grid-connected voltage source converters. The capacitor voltage derivative active damping effectively damps the ...
Active damping based on the capacitor voltage positive-feedback for grid-connected power converters with LCL filter
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
The capacitor voltage positive-feedback is a widely extended active damping strategy. It can effectively damp the LCL output filter resonant poles for low ratios of resonance to sampling frequencies. However, the existing ...
