ABSTRACT In the existing technique for power electronic converters with low switching frequency and multiple cells, the sampling frequency is always set at the same value as the control frequency, and the modulating wave in each cell updates itself when its...
ABSTRACT This paper proposes a novel DC power electronic transformer (DCPET) topology for locomotive, AC/DC hybrid grid, DC distribution grid and other isolated medium-voltage and high-power applications. Compared with conventional PET topology, the proposed DCPET has...
ABSTRACT This paper presents a Unified Power Flow Controller (UPFC) application of the Custom Power Active Transformer (CPAT); a power electronics integrated transformer which provides services to the grid through its auxiliary windings. The CPAT structure integrates...
ABSTRACT This paper proposes an analytical methodology to evaluate the power processed by dc-dc converters operating as series voltage regulators, which provide an alternative to increase efficiency in photovoltaic systems. Via the analysis of both active and...
ABSTRACT This paper describes the solution for monitoring and control of power electronics devices in telecommunication facilities. Centralized monitoring of the power supply system enables monitoring of the operation of all devices in the system, using the same user...
ABSTRACT In this paper, a DC-DC multi-port converter is introduced by integrating a super-lift and a buck converter (SLBC). The proposed single-input dual-output (SIDO) converter has conventional positive output voltage super-lift advantages while simultaneously...
