Poly-phase systems have been used for many years in machines and recently in wind power generations. Typically, this system employs diode rectifiers, however, it may be improved employing active rectifier. Considering it, this paper proposes a six-phase active rectifier topology controlled in synchronous frame reference. Results were validated by simulation.
This paper proposes a method for calculation of the instantaneous active and reactive power in six-phase system, derived from the Akagi three-phase instantaneous power theory, the proposed method is physical analyzed and the results are validated by simulation.
In UPS applications VSI parallel connected is a very common solution to improve the power capability and the reliability of the system, however, a strategy to share the load current should to be used. In this work a control strategy, with communication, is proposed for three-phase four-wire VSIs parallel connected.
This paper approaches the implementation of a control strategy with communication for three-phase four-wire VSI parallel connected, which is based on distributed control. The paper presents details of implementation of one control strategy that employs two loops, one voltage control and one parallelism control, all system is done on instantaneous values and the parallelism control shares only a voltage...
This paper describes a theoretical and experimental study on a digital communication system, which is employed in a control strategy for parallelism of three-phase voltage inverter (VSI). This control strategy only needs that all VSIs use a same voltage reference and thus it ensures the sharing of the load current and avoids current circulation among the inverters during transient and steady-state...
