“…As for the control strategy, the power decoupling control based on the BBDC can be performed by either the directpower-decoupling method or automatic-power-decoupling method [20]. Almost all the direct-power decoupling methods are calculating the resonating power in an open-loop manner [11], [17], [21]- [26]. The open-loop manner is easy to implement, however, it is sensitive to variations of parameters and disturbances.…”

For the single-phase high-power railway traction system, the inevitable second-order resonating power has become a critical issue to the traction system. In this paper, a power decoupling solution is proposed to replace the conventional passive LC resonance filter by utilizing the buck-type bidirectional DC/DC converter (BBDC) of Hybrid Electric Multiple Units (HEMU), which is designed to power the train in non-electrified routes using the on-board battery. By considering both the current ripples in the battery mode and the power decoupling in the catenary mode, the corresponding parameter design process of the BBDC is presented. Based on the power coupling phenomenon and the spectrum characteristic of the BBDC, a direct resonance control method is proposed to decouple the low-order resonating power. Simulations and experiments are carried out to validate the effectiveness of the new proposal. The results demonstrate that the proposal is almost the same as using the conventional passive LC resonance filter for power decoupling in both steady and dynamic operation scenarios. 1

“…The control utilizes the peak-value of ripple storage capacitor, therefore a peak detector is required to realize the peak voltage control. An application of buck-boost type APT along with zero voltage switching is proposed in [138] to reduce the switching loss also.

This paper provides a comprehensive review of the control approaches and the powerdecoupling topologies to mitigate 2ω-ripple problem in the single-phase inverters, its solutions, and discusses open challenges yet to be addressed. The cause and effects of 2ω-ripple problem and its solution based on the passive and active power-decoupling techniques are discussed. A subcategory of the active power-decoupling technique nominated as the control-oriented compensation technique is reviewed in detail, this technique can achieve the ripple-mitigation at the source through the control but not necessarily adds extra circuit or active filter to the system. The control-oriented compensation techniques can be applied in the two-stage DC-DC-AC converters and the single-stage inverters having a front-end control capability with the H-bridge such as in the quasi-switched-boost inverters. The merits and associated challenges of these techniques are listed and summarized in a tabular form. Finally, a conclusive discussion with open challenges is presented. INDEX TERMS 2ω−ripple, Single-phase Inverter, Control strategies, Power-decoupling schemes.

“…According to whether the decoupling unit and the original converter switch are multiplexed or not, the active decoupling topology can be divided into dependent decoupling and independent decoupling. The independent decoupling circuit usually keeps working independently with the original converter [3][4][5][6][7][8][9][10][11][12]. However, independent decoupling usually requires more switching control capacitors or inductance compensation systems for double frequency power.…”

“…There is also an option to compensate for the double frequency in the form of a series H bridge in the system [4], 5. Literature [1][2][3][4][5][6][7][8][9][10] adopts the method of using a buck circuit as an independent decoupling unit on the DC side. In addition to using the basic circuit as an independent decoupling unit, literature [11], 12 adds a bridge arm on the DC side to control a group of split capacitor voltages to achieve the purpose of compensation.…”

Single-phase inverters have a wide range of applications in many fields, but there are inherent double frequency problems, and double frequency fluctuations can easily cause system instability. This paper proposes a mid-point common-mode injection power decoupling circuit. The advantage of this topology is that there are no additional switching devices and only the original DC side support capacitors and filter capacitors of the H-bridge inverter can be used to buffer the double frequency power. The half-bridge structure of this topology enables the AC side capacitors to operate positively and negatively, which can reduce the selection of the withstand voltage of the decoupling capacitor. Simulation and experimental results prove that the method can effectively suppress the secondary ripple on the DC side. The final data shows that the topology can effectively improve the system efficiency after decoupling.
