This paper proposes an energy storage unit integrated dual input PV system with distributed maximum power point tracking (MPPT). Through applying a symmetrical configuration, the proposed PV system has a single stage structure to implement voltage boosting and inversion, which contributes to the advantages such as compact size and high power conversion efficiency. The design of the control strategy...
Common variable speed drives usually do not feature regenerative braking. The energy produced during deceleration is dissipated through braking resistors. In this paper, a bidirectional converter designed for use with variable speed drives, adding the capability of regenerative braking, is presented. Hardware design and control algorithms are analyzed and comparison with similar proposals is made...
This paper proposes a high-performance line-interactive DVR which can compensate the voltage interruption within 2 ms. The operational feasibility was verified through computer simulations and experimental works with a 3 kVA prototype. The developed system can compensate the input voltage sag and interruption within 2 ms, in which the maximum allowable duration of voltage interruption is 2 seconds...
