The fundamental phase shift compensation scheme in a digital-controlled VIENNA rectifier with variable carrier-fundamental frequency ratio under unbalanced grid conditions

Energy Reports, 2022
In the DC power distribution systems, One-cycle control (OCC) based three-phase VIENNA rectifiers achieves high power factor (PF) easily. However, under unbalanced grid conditions, the fundamental phase shift between the input current and corresponding ...

Small-Signal Modeling for Phase-Shift Controlled Resonant Converters

IEEE Transactions on Industrial Electronics, 2021
The extended describing function (EDF) method is widely used in modeling the resonant converters. This article finds that the model of the phase-shift controlled resonant converter deduced by this method might be inaccurate especially when the duty-cycle is close to 1. The reason behind it is investigated, showing that derivation of the inverter bridge

Harmonically-related diffraction gratings-based interferometer for quadrature phase measurements [PDF]

, 2006
We demonstrate the use of shallow diffraction gratings for quadrature phase interferometry. A single shallow diffraction grating-based Michelson interferometer yields only trivial (0° or 180°) phase shift between different output ports.
