Small-Signal Modeling for Phase-Shift Controlled Resonant Converters
IEEE Transactions on Industrial Electronics, 2021The 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

Thyristor-controlled phase-shifting devices
Russian Electrical Engineering, 2014Phase-shifting devices with thyristor regulation intended for the constant control of power overflows in power-supply networks with parametric and regime nonuniformity have been developed. The phase shift of the output voltage is regulated using a high-voltage thyristor key, which ensures the speed of the device.

Digital control for phase shift converter
Proceedings of 2012 IEEE International Conference on Automation, Quality and Testing, Robotics, 2012The development of intelligent microgrids with renewable energy sources increased significantly nowadays. The present paper examines and compares analog and digital control of a bidirectional phase shift converter in order to find out which is best suited to be used in intelligent microgrid applications.

Controlling Power Flow with Phase Shifting Equipment
Transactions of the American Institute of Electrical Engineers, 1930In the operation of an electric power distributing system involving various kinds of networks, a fundamental necessity is that each transforming and transmitting unit carry a reasonable share of the total load. In the case of a single system that has been developed in a coordinated manner the problem of load division has not in general been troublesome

CONTROL OF STATIC PHASE SHIFTING TRANSFORMERS WITH LEAKAGE REACTANCE
IFAC Proceedings Volumes, 1983Abstract Analysis has shown that a phase shifting transformer can enhance the stability of a power system. Methods of adjusting phase shifting transformers and control algorithms to realize the stability improvement have been demonstrated. However, in earlier work the effect of leakage reactance and reactance inserted to limit fault currents has not ...

Reconfigurable Impedance Matching Networks With Controllable Phase Shift
IEEE Transactions on Circuits and Systems II: Express Briefs, 2018Two kinds of reconfigurable impedance matching networks with controllable phase shift are proposed. The reconfigurable networks can match different loads with desired phase shift at center frequency and no extra phase shifter is needed. The two networks are realized by using varactor diodes and switches, respectively.

Phase-shifting (Sagnac) interferometer with external phase control
Applied Optics, 2005A novel ring configuration for phase-shifting interferometry with external phase-shifting control is presented. The device is a polarization (ring) interferometer, in which the reference and test arms are parts of the same collimated beam. The key point is to manage the polarization of the light such that orthogonal linear polarizations describe ...

Phase-shift control in electro-optical analyzers
SPIE Proceedings, 1994Adjustment and stabilization of an optimal value of control voltage is a common problem in spectrum polarimetry when using electrooptical polarization analyzers. In this paper we give a description of a method to determine the quarter-wave phase shift when handling control signals of square form (of the type of a `meander').

Voltage-Controlled Phase Shift of Triangular Waves
IEEE Transactions on Instrumentation and Measurement, 1973A principle is described whereby an instantaneous voltage proportional to the phase shift of the outputs of two triangular-wave generators can be obtained. By controlling one of the triangular-wave generators with the difference between this voltage and a reference voltage, a certain phase difference between the triangular waves is obtained which can ...
