High efficiency and fast dynamic response are two main control objectives for dual active bridge (DAB) DC-DC converters. Traditional extended phase shift (EPS) control can significantly enhance the conversion efficiency of DAB DC-DC converters by reducing current stress; however, it cannot fulfill fast dynamic response requirements. In this paper, a novel hybrid control scheme consisting of EPS control and direct power control (DPC), named as EPS-DPC, is proposed. EPS-DPC control has salient features in both efficiency and dynamic performance. In order to verify the outstanding performance of the proposed EPS-DPC scheme, an experimental comparison was carried out on a scale-down DAB DC-DC converter among several control strategies, including single phase shift control with traditional voltage-loop (SPS-TVL), EPS control with traditional voltage-loop (EPS-VTL), and EPS-DPC. Experimental results have been high consistent with theoretical analysis, and verified these advantages of the proposed EPS-DPC scheme.

“…Locomotives transformer topology, losses and their reduction can be found in [1]. Single phase H-bridge inverter (used as a single-phase shunt active power filter) has a wide range of applications such as converters connecting renewable energy sources (typically solar cells) to an ac power [2] or different kinds of active power filters for reducing of harmonic distortion in power grid [3] and also secondary single-phase converter in locomotive with medium-frequency transformer as a specified in [4]. A detailed analysis of negative effects caused by distorted current waveforms can be found in [5].…”

This research has been motivated by industrial demand for modernization of older types of DC motor locomotives powered from AC line. The paper describes control algorithm of additional filtering system for DC motor locomotives based on shunt active power filter (APF). The single-phase shunt active power filter reduces harmonic distortion of AC-line current and thus reduces losses in traction transformer and trolley-wire. The proposed control algorithm of APF consists of hysteresis current controller with an adaptive multiplicative general parameter finite impulse response filter (MGP-FIR) as a precise current reference generator. Behaviour of designed control is analyzed by experiments on developed laboratory prototype.Index Terms-Power converter, Single-phase shunt active power filter, DC motor locomotive, harmonic distortion,

This paper deals with topology of indirect frequency converter for new mining machine drive fed directly by 6kV ac power grid. The proposed topology is composed of input cascaded H-bridge active rectifier and output cascaded Hbridge inverter. The main attention is paid to control of input cascade H-bridge active rectifier especially to voltage balancing of the individual power cells (H bridge). The proposed control uses conventional PWM with shifted carriers and voltage balancing is solved separately by control algorithm. The paper describes results of the simulation tests for designed low-voltage laboratory prototype of rated power of 10 kW.
