Modeling of cascade buck converters
نویسنده
چکیده
In this paper signal flow graph non-linear modeling of cascade buck converters is presented. Unified signal flow graph model of the converter is developed and then deduction of large, small-signal and steadystate models from the unified graph is demonstrated. Converter performance expressions are derived. Largesignal model is developed and programmed in TUTSIM simulator. Large-signal responses against supply and load disturbances are obtained. Validity of the proposed signal flow graph modeling is verified through PSIM simulator results.

Optimized Cascade PI Controllers of Buck Converters Using Particle Swarm Optimization Algorithm
This paper presents the optimal controller design of buck converters. The particle swarm optimization algorithm is applied to tune the controller parameters until the best output response is achieved. The output response from the system with the controllers designed by the proposed technique is compared with those from the classical method. The transient simulations using the commercial softwar...
متن کاملA Novel Method for Modeling and Simulation of Asymmetrical Impedance-source Converters
Z-Source converter or impedance-source converter is a kind of power converters, which has the responsibility to convert the direct current to alternative current. This converter with respect to its circuit diagram acts as a buck-boost converter except it doesn’t use from DC-DC converter bridge. Γ-source inverters are one of the conventional converters based on impedance-sources; which have been...
متن کاملOn the robust linear control of the "buck-buck" converter: An active disturbance rejection approach
In this article, the cascade connection of two “buck” converters is examined from the perspective of differential flatness and Generalized Proportional Integral (GPI) observer–based control. The multi-variable nonlinear “buckbuck” converter is subject to unknown, time-varying, load current demands, at each one of the outputs of the two constitutive stages. The linear output feedback controllers...

In this paper, a novel approach for control of the DC-DC buck converter in high-power and low-voltage applications is proposed. Designed method is developed according to passivity based controller which is able to stabilize output voltage in a wide range of operation. It is clear that in high-power applications, parasitic elements of the converter may become comparable with load value and hence...
متن کاملA State-space Modeling of Non-ideal Dc-dc Converters
A modeling based on the practical switches with finite turn-on, turn-off, delay, storage and reverse recovery times is proposed. The switching effects on the state equation, system stability, dc gain and efficiency are shown for the boost, buck and buck-boost converters. The effect of switching time variation by current on system stability is given as an extension of the storage time modulation...
