Summary: This article proposes a bidirectional transformerless multilevel direct ac-ac switched-capacitor converter (SCC) with both in-phase and out-of-phase output voltage capabilities. The converter reduces voltage and current stresses of the components, leading to higher efficiency and lower manufacturing costs. The interleaving control scheme provides lower current ripples and smaller filter sizes. Experimental results show that the converter achieves stable output voltages with high efficiency.

Summary: Power quality issues such as voltage sag, voltage swell, voltage transients, voltage interruptions, and harmonics have global impact on industries. Solutions like DVR and Matrix Converter are effective in addressing voltage sag, with the latter offering better performance by directly converting AC to AC voltage without the need for energy storage, reducing costs and complexity. Control circuits are crucial for maintaining constant voltage at load points, with nonlinear controllers essential for satisfactory DVR performance.

Summary: This paper proposes a DVR based on a self-coupled PI controller, which can detect voltage sag in real-time and provide fast compensation. The system's disturbance rejection and robustness are improved by the cooperative control of output and given deviation through the controller speed factor. Simulation results show that the DVR based on SC-PI has faster response time, lower voltage variation, and reduced harmonic distortion compared to traditional PI control.

Summary: This letter proposes a novel modulation method for the indirect matrix converter (IMC) by decoupling the rectifier and inverter, greatly simplifying the modulation of the IMC. The inverter uses a space vector modulation without a zero-voltage vector to adjust the phase of the output voltage vector, while the rectifier adopts a novel delta-sigma method to modulate the input current vector phase and dc-link voltage. The duty cycles of the inverter are obtained by looking up a table of reference output voltages and updated at a 5-kHz carrier cycle, while the switching states of the rectifier change once per cycle at a 40-kHz sampling frequency. Simulations and experimental results are presented to validate the proposed method.

Summary: A new topology is proposed in this paper to regulate voltage sags/swells in the distribution network. Voltage sags and swells are major power quality issues in the power industry. The traditional voltage restorer based on energy storage devices is not sufficient for compensating deep and long-duration voltage sags/swells. To solve this problem, a novel bipolar direct AC/AC type voltage restorer (AC/AC-VR) topology is proposed, which has bipolar regulation ability and no storage device. The proposed topology is demonstrated through analysis, simulation, and experimental results.
