A Modified Push-Pull Topology with Phase-shift Modulation
International Symposium on Power Electronics for Distributed Generation Systems, 2021This paper presents a DC-DC converter based on Push-Pull converter configuration. These converter circuits are broadly classified into three categories i.e., Pulse Width Modulated (PWM) current-fed, PWM voltage-fed, and based on single phase-shifted ...

State Trajectory Analysis for LLC Resonant Converter Under Phase-Shift Modulation
2024 IEEE China International Youth Conference on Electrical Engineering (CIYCEE)The LLC resonant converter can be utilized in the new energy vessel power systems, connecting new energy sources and power batteries or daily loads. Employing a phase-shift modulation (PSM) strategy instead of pulse frequency modulation (PFM) can enhance

Higher-order differential phase shift keyed modulation
IEEE Transactions on Communications, 1994Advanced modulation/demodulation techniques which are robust in the presence of phase and frequency uncertainties continue to be of interest to communication engineers. The authors are particularly interested in techniques which accommodate slow channel phase and frequency variations with minimal performance degradation and which alleviate the need for

Reactance Tube Modulation of Phase Shift Oscillators
Bell System Technical Journal, 1949This paper describes a basic circuit for reactance tube modulation of phase shift oscillators. The design of suitable phase shift oscillators for frequencies from audio through the ultra-high frequencies is discussed. Experimental performance data derived from several types of frequency modulated phase shift oscillators are presented.

The Novel Single Phase-Shift Modulation Scheme for Dual Active Bridge Converter
2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020For the dual active bridge (DAB) converter, the single-phase shift (SPS) modulation scheme is simple and easy to control the transmission power. However, the zero-voltage switching (ZVS) operation is lost at the light load condition and the sizeable ...

Modulation analysis of phase-shifted holographic interferograms
Optics Communications, 1994Abstract A new evaluation technique for phase-shifted holographic interferograms is developed and verified by experiments. In evaluating the interferograms, both the discrete phase distribution and the intensity modulation of interference fringes are calculated and a binary control mask is generated by analysing histograms and tracing local minima of

Experimental demonstration of microring quadrature phase-shift keying modulators
Optics Letters, 2012Advanced optical modulation formats are a key technology to increase the capacity of optical communication networks. Mach-Zehnder modulators are typically used to generate various modulation formats. Here, we report the first experimental demonstration of quadrature phase-shift keying (QPSK) modulation using compact microring modulators.

Small-Signal Modeling of Uniformly Sampled Phase-Shift Modulators
IEEE Transactions on Power Electronics, 2014Phase shift modulation (PSM) is a commonly used technique for controlling the active power flow in resonant dc-ac and dc-dc converters. Although traditionally developed as an analog modulation scheme, digital PSM is being increasingly used in conjunction with advanced multi-variable digital controllers and online efficiency optimization algorithms ...
