Duty Cycle Prediction Control Based DPWM Strategy for Electrolytic Capacitorless Vienna Rectifier

IEEE transactions on industrial electronics (1982. Print)
Replacing electrolytic capacitors with film capacitors on the dc link can significantly improve lifetime of Vienna rectifier. However, the reduction of capacitance leads to the increase of neutral point (NP) voltage fluctuation, increasing the voltage ...

Three-Phase VIENNA Rectifier Interval Control Strategy to Improve Light Load Performance

IEEE Journal of Emerging and Selected Topics in Power Electronics
The three-phase VIENNA rectifier operates in a low-power standby mode for a long time, where fluctuations in the dc output voltage will lead to reduced system performance and reliability. Therefore, stability in light load conditions is crucial.

Switch Open-Circuit Fault Diagnosis of the Vienna Rectifier Using the Transformer–BiTCN Network with Improved Snow Geese Algorithm Optimization

Electronics
The switch open-circuit fault signal of the Vienna rectifier possesses non-stationary characteristics and is also vulnerable to external interference factors, such as sensor noise and load variation. This phenomenon reduces the performance of traditional

A Hybrid Control Scheme for Three-Phase Vienna Rectifiers

IEEE Transactions on Power Electronics, 2018
Vienna rectifier is a kind of power converter with complicated operating constraints. Thus, it is difficult to control with conventional control strategies, especially during transients or under low power factor operation. This study proposes a hybrid control scheme with dual loops for the three-phase Vienna rectifier.

Zero Common-Mode Voltage Modulation for Flying-Capacitor-Based Vienna Rectifier With Consideration of Nonideal Factors

IEEE transactions on industrial electronics (1982. Print)
This article analyzes the common-mode voltage (CMV) of the Vienna rectifier and proposes a CMV elimination strategy. The proposed method reduces the neutral-point voltage (NPV) fluctuation by introducing an auxiliary flying capacitor (FC) leg and ...

A Direct Modulation Index Control Strategy for Three-Phase Vienna Rectifier at Light Load

IEEE transactions on power electronics
The three-phase Vienna rectifier suffers from the inherent problem of increased or unstable output voltage on the dc side at light loads. In this article, a light-load state judgment criterion is derived based on the Vienna equivalent model.

Research on Direct Power Control of Vienna Rectifier Based on Sliding Mode Control

2025 6th International Conference on Clean Energy and Electric Power Engineering (ICCEPE)
The three-phase Vienna rectifier offers structural simplicity, low switching loss, and high power density, but traditional PI control suffers from poor robustness, slow dynamics, and midpoint voltage fluctuations. This paper proposes a sliding mode-based
