The single-phase isolated quasi-single-stage AC-DC converter has many virtues, such as high power density and efficiency; however, its grid current closed-loop control has not been solved. This paper aims to solve the remaining gap based on a large-signal model. In this paper, the large-signal model of this converter under triple-phase-shift modulation is built for the first time. It is verified that the built model is a zero-order linear system. Based on this built model, the effect of grid harmonics on this converter grid current is analyzed. The theoretical analysis reveals that the grid voltage low-order harmonics will cause the same order grid current harmonics and only varying the parameters of the filter is not an effective method to solve this problem. For the purpose of eliminating the effect of grid voltage harmonics on the grid current and realizing the zero-error control of the fundamental component of the grid current, a grid current closed-loop control strategy based on the proportional-resonant compound odd-mode repetitive controller is proposed. The operation principle, parameter constraint, and design rule of the proposed compound control strategy are analyzed comprehensively. The theoretical analysis and the compound control strategy put forward in this paper are tested, with detailed experimental results. Full article

With the improvement of technology, the demand for electrical power continues to deepen. Wireless Power Transfer (WPT) technology can transmit power without using physical media such as cables, and it has the advantages of electrical isolation, convenience, and safety. At present, the miniaturization of the secondary side is an emerging trend of WPT systems, which is analyzed in this paper. By introducing an interleaved boost converter in the front stage, the DC bus voltage of the primary side is increased, the loss of the primary side is reduced, and the system efficiency is improved. At the same time, the self-inductance of the primary and secondary sides of the loosely coupled transformer is designed to meet the stress requirements of passive devices and the realization of a closed-loop system. Finally, a WPT system with an input voltage of 100 V, an output voltage of 100 V and a transmission power of 500 W is built. The transmission distance of this system is 170 mm, with a lateral offset of 200 mm and a vertical offset of 100 mm. After the offset of the primary and secondary sides, the output voltage can be stabilized at 100 V, and the system efficiency can reach 90.1%, which proves the feasibility of the system efficiency improvement strategy and the effectiveness of the closed-loop control.

In this paper, a triple-active-bridge resonant dc-dc converter with the ability of topology-level power decoupling is proposed. The power coupling between the two dc ports is eliminated by adding a resonant capacitor to the common port. The operation principle and the steady-state power characteristics are analyzed. On this basis, a multi-phase-shift-based global optimization modulation is proposed to minimize the RMS values of the transformer currents in the entire power and voltage range, thus increasing the global efficiency. An experimental prototype is built to verify the correctness and availability of the proposed power decoupling topology and optimized modulation. Full article

This paper proposes the fast and accurate electro-thermal model of the existing Simrod three-phase inverter for an electric vehicle (EV) application. The research focuses on analytical and dynamic electro-thermal models of inverters that can be applied for multi-applications. The optimal design approach of passive filters is presented for the DC and AC sides of the inverter. The analytical model has been established, including a mathematical representation of the inverter and induction motor (IM). The high-fidelity electro-thermal simulation model of an inverter with integrated power loss and thermal model is established. The state-space thermal model (for the IRFS4115PbF device) has been created and incorporated into the MATLAB simulation. The simulation model is then validated with the PLECS software-based thermal model to confirm the accuracy. Indirect field-oriented control (IFOC) is designed for squirrel-cage IM at a maximum power rating of 45 kW and implemented on MATLAB/Simulink. The comparative analysis between the real and simulated results is performed to validate the simulation model at a specific speed, torque, and current. Furthermore, the electro-thermal simulation model has been validated with experimental data using efficiency and temperature comparison. The developed simulation model is beneficial for designing, optimizing, and developing advanced technology-based inverters to achieve higher efficiency at a particular operating range of temperature and power quality. The new European driving cycle (NEDC) speed profile simulation results are demonstrated. Full article

To suppress the harmonics of series-connected 18-pulse rectifier, a hybrid harmonic suppression method is proposed in this paper. According to the structure of the converter and the KVL, the injection voltages are expressed. According to the injection voltages, the relation between the input voltage THD and the injection transformer turn ratio is obtained. Based on the relationship, when the THD of the input voltage researches the lowest value, the optimal injection transformer turn ratio is determined. Testing result shows that after using the proposed reduction method, the input side THD values of the converter are reduced. The capacity of the suppression circuit is only about 2% of the load power. The proposed converter is qualified for the interface between the AC generator and the DC bus of the aircraft electrical system. Full article
