Discontinuous Conduction Mode Analysis of Phase Modulated Series Resonant Converter

چکیده
This paper proposes an analytical approach to derive voltage gain for phase modulated (PM) dc-dc series resonant converter (SRC) operating in discontinuous conduction mode (DCM). Conventional fundamental harmonic approximation (FHA) technique is extended for non-ideal series resonant tank. The DCM analysis is presented in a normalized form defining appropriate base quantities. The converter is analyzed both in time and frequency domain to derive a non-linear algebraic function of diode rectifier extinction angle. The root of this function is numerically determined using MATLAB and used to predict the dc bus voltage. Experimental results are presented to validate the analysis.

Voltage Regulation of DC-DC Series Resonant Converter Operating in Discontinuous Conduction Mode: The Hybrid Control Approach
Dynamic modeling and control of dc-dc series resonant converter (SRC) especially when operating in discontinuous conduction mode (DCM) is still a challenge in power electronics. Due to semiconductors switching, SRC is naturally represented as a switched linear system, a class of hybrid systems. Nevertheless, the hybrid nature of the SRC is commonly neglected and it is modeled as a purely contin...

متن کاملAnalysis of New Transformerless dc-dc Converter With High Voltage Gain
In some industries applications such as fuel cells, we must use a high voltage gain dc-dc converters for increasing voltage, but, the conventional converters cannot provide the high voltage gain with increasing duty cycle and the converters efficiency is limited by the equivalent series resistances. For this reason, in this paper, a single switch transformerless high step-up dc-dc converter wit...

متن کاملA Unified Analysis of PWM Converters in Discontinuous Modes
Three discontinuous operating modes of PWM converters are considered in this paper-the discontinuous inductor current mode (DICM), the discontinuous capacitor voltage mode (DCVM) and a previously unidentified mode named discontinuous quasi-resonant mode (DQRM). DC and smallsignal ac analyses are applicable to all basic PWM converter topologies. Any particular topology is taken into account via ...
