Control Strategy for Buck DC/DC Converter Based on Two-dimensional Hybrid Cloud Model

In order to adapt the fast dynamic performances of Buck DC/DC converter, and reduce the influence on converter performance owing to uncertain factors such as the disturbances of parameters and load, a control strategy based on two-dimensional hybrid cloud model is proposed. Firstly, two cloud models corresponding to the specific control inputs are determined by maximum determination approach, r...

An Improved Control Method Based on Modified Delta-Sigma Modulator for Buck Converter

This paper proposes an improved control method based on modified Delta-Sigma Modulator (DSM) to enhance transient response and improve harmonic contents of buck DC-DC converter. The main advantages of the proposed method are improving the output voltage frequency spectrum, correction of the output voltage harmonic contents and sideband harmonics, reduction of switching noise peaks at the output...

Multiple model control of a Buck dc/dc converter

This paper describes a simple model estimator for a new control method based upon algorithms commutation between two linear control laws. The multiple model control (MMC) defined is based upon the fusion of only two traditional IP controllers outputs. The influence of the digital integration methods and of the noise are pointed out. This new strategy improves the performances of the step input ...

A New Structure of Buck-Boost Z-Source Converter Based on Z-H Converter

In this paper, a new structure for buck-boost Z-source converter based on Z-H topology is proposed. The proposed converter consists of two LC networks similar to the conventional Z-source and Z-H converters. One of the characteristics of the proposed structure is that, without any changing in its’ power circuit, it can be used in different conversions such as dc/dc, dc/ac and ac/ac. This unique...
