Power electronic transformer (PET) with modular cascaded structure has become a flexible interface between AC and DC grids. Nonetheless, the notable 2 nd-order ripple power introduced from the AC source requires considerable energy storage in the module capacitors, which is likely to degrade the overall power density and increase system cost. In this paper, a power channel based four-winding PET (PC-PET) is proposed to address such an issue. Owing to the phase-crossing power channels, the low-frequency ripples can cancel each other through magnetic flux counteracting. To improve the accuracy of power decoupling, the effect compromised by inconsistent windings is considered. Accordingly, a proportional-resonant (PR) control based power decoupling strategy for PC-PET incorporated with power balance is proposed to decouple the three-phase low-frequency ripple powers, and minimize the voltage ripple in module capacitors. Additionally, the improvement of power density is discussed based on analyses on power losses, capacitor volume and transformer volume. Simulation and experimental results verified the validity of proposed control strategies.

The paper is talked about a new current tracking control method for low-voltage high-power active power filter. The main circuit topology of APF adopts a three-phase three-line voltage source converter which is constituted by three H-bridges. Current tracking control method of APF determines the APF performance. For high-power APF, the switching frequency of APF system is difficult to improve, resulting in a relatively narrow control bandwidth of the current loop, which affects the stability of the APF. How to solve the system switching frequency and system control bandwidth contradictions become critical. This paper presents a new hybrid control strategy, which can achieve the ideal control effect of harmonic suppression and unbalanced reactive power compensation.

In this paper, a voltage oriented control strategy for three-level PWM rectifier based on Sliding Mode Control (SMC) is introduced in order to obtain fast and accurate response of dc-bus voltage. To verify the validity of the analysis and the feasibility of the proposed control method a set of simulation tests have been conducted using Matlab/Simulink. The simulation results show that compared to the conventional PI controller, the SMC can reduce drastically the three-level rectifier's voltage fluctuation and improve the dynamic response of dc-bus significantly.
