This paper proposes a boost dc-dc converter topology with the capability of canceling the input current ripple at an arbitrarily preselected duty cycle, high-voltage gain without utilizing extreme values of duty cycle or boosting transformers, it contains a switched-capacitor structure in which the current among capacitors is continuous. The paper provides details on the principle of operation via...
The daily variation of power system loading, increasing demand for electrical energy and contingencies may lead to poor voltage profiles of the system. Among several voltage control means, an Static VAr Compensator (SVC) based on Naturally Saturated Reactors (NSR) can be used to improve the voltage level at a given bus by the injection or absorption of reactive power. Furthermore, Optimal Power Flow...
Capacitor banks are installed to compensate the reactive energy demanded by the local loads or feeder reactance, in order to adequate the voltage and technical losses. Although those benefits of installing capacitor banks in feeders are incontestable, the engineers should consider the harmonic resonance effects and the possibility of this resonance to increase the voltage distortion to levels above...
This paper proposes a modification on the Hybrid Active Series Filter (HASF) creating a topology named Hybrid Active Var Compensator (HAVarC) suitable to manipulate, in continuous way, the displacement power factor or voltage regulation. The HAVarC is composed by a small rating Active Power Filter (APF) in series with a capacitor bank. The main objective of this topology is to control the reactive...
This paper describes the technique developed to charge and to regulate the hybrid active power filter link DC. The developed strategy is based on the Modified Synchronous Reference Frame Controller. The ability of the hybrid topology in charging and regulating its own Link DC without external sources connection is analyzed. The accuracy and the dynamics are presented, and the measurements of active...
