Design and control of modular multilevel matrix converter with symmetrically integrated energy storage for low frequency AC system

open access: yesIET Renewable Power Generation, Volume 18, Issue 1, Page 60-77, 6 January 2024.
Modular multilevel matrix converter with symmetrically integrated energy storage for low frequency AC system is investigated in this paper. An evaluation method for the minimum required number of active submodules is presented, and the influences of operating conditions on the minimum required number of active submodules are studied.

Fryze reactive power of trams in effective stochastic recuperation processes

open access: yes, 2019
Urban electric transport system, particularly tram systems, is not a direct current system not only in traction mode but in regenerative modes as both voltage on a collector and regenerative current are stochastic abruptly variable processes.

Analysing two control methods of shunt active filters for unbalanced load [PDF]

open access: yes, 2014
A three-phase shunt active filter is used for current and/or voltage unbalance compensation. Two control schemes with two different theory, instantaneous power theory and Generalized Fryze are considered to compensate the unbalance of current, voltage,
