“…For an ac-fed railway traction drive, this means beat components in the stator current of the ac machine, the frequencies of which are the sum and difference of the dc-link ripple frequency and the output frequency. The beat currents bring extra power losses, temperature increases, torque pulsations, and audible noise [3], [4].…”

Single phase converters suffer from ripple power pulsating at twice the line frequency. The ripple power is usually absorbed by a bulky capacitor bank and/or a dedicative LC resonant link, resulting in a low power density and a high cost. An alternative solution is using a dc link active power filter (APF) to direct the pulsating power into another energy-storage component. The main dc link filter capacitor can then be reduced substantially. Based on a mainstream dc APF topology, this paper proposed a new control strategy incorporating both dual-loop control and repetitive control. The circuit parameter design is also re-examined from a control point of view. The proposed APF scheme has better control performance, and is more suited for high power applications since it works in CCM and with a low switching frequency.

“…Mainly the double-frequency ripple power will cause degenerated lower efficiency and overheating when a solar PV system or a BESS is connected to the dc-side voltage [7][8][9]. In addition, the double-frequency ripple power will generate the beat phenomenon in the motor current of the ac-fed railway traction drive system, which causes power loss, torque pulsation, and audible noise [10,11].…”

In this paper, a generalized switching function-based space vector modulation (SVM) algorithm is presented and evaluated to minimize the dc voltage utilization and the ac utility grid current total harmonic distortion. This paper explores the control and modulation techniques of a single-phase three-leg converter with an active power decoupling method, where a generalized SVM algorithm is proposed and evaluated for easy implementation in a digital control platform. The active power decoupling method with the proposed converter can be achieved via dependent control and modulation techniques. The control method is separated into the ac active power control part and the dc power ripple control part, which can maintain a unity power factor at the ac utility grid and reduced the double-frequency ripple power effect on the dc-side. Simulation results validate the performance of the modulation algorithm and its control and demonstrate the feasibility of the proposed power converter, as well as the two mentioned operation modes of the power converter.

“…These oscillations degenerates the quality of power processing and are present in both operation mode: rectifier (AC-DC converter) and inverter (DC-AC converter). Side effects can be seen in several applications [1]- [5] and [6]. There are lots of situations that it is desirable to avoid power oscillation at the DC-link.…”

This work proposes a technique to reduce the low frequency DC-link energy oscillation due to the pulsating singlephase energy flow in a single-phase to single-phase Voltage Source Converter (VSC) and Current Source Converter (CSC) which operate connected to the grid. That pulsating energy is the major responsible for increasing the size of the passive components and power losses in the converter. The pulsation reduction is achieved by incorporating two auxiliar active switches and one passive energy storage element to the rectifier and inverter side. Additionally, this paper presents the comparison of these convertes regarding efficiency and power density. Details control strategy is presented. Simulation and experimental results are provided to validate the theoretical approach.
