Transient Performance Improvement of Boost Converter using Sliding Mode Controller

Suitable controller design for Boost converter is important to increase its performance in various applications like renewable energy integration and control circuitries. Linear controller are proved to be inefficient under varying operating conditions. Sliding Mode Controller (SMC) is a nonlinear controller offering advantages of robustness, fast dynamic response and ease of implementation. In this research work, SMC for Boost converter is proposed and analyzed using MATLAB® SIMULINK® as simulation platform. State space modelling technique is used for Boost converter. Proposed SMC comprises of two loops; voltage and current, controlled by Proportional Integral (PI) and Hysteresis respectively. Simulation of Boost converter with proposed controller shows good response in terms of less overshoot and settling time for initial transient, supply, load and reference variations.

Modelling and Simulation of Boost Converter with Maximum Power Point Tracking (MPPT) for Photovoltaic Application

This paper presents the proposed model and simulation of a DC to DC converter with maximum power point tracking (MPPT) using fuzzy logic controller (FLC) for a standalone Photovoltaic (PV) System. This research will focus on the developing high performance DC to DC converter with fuzzy logic controller based to extract the maximum power that generated by the PV panel. The system composed of the PV array and DC-DC boost converter with MPPT system. The maximum power point tracking control is based on adaptive fuzzy logic to control ON/OFF time of IGBT switch of DC-DC boost converter. The proposed DC to DC converter is designed by using the Multisim software while the controller programme will be carried out by using the Matlab Simulink software. Pulse width modulation will be generated by the controller to trigger the IGBT gate. The performance of the proposed model is evaluated by the simulation and the result show that our proposed converter can convert more power from generated voltage. By using the fuzzy logic method to track the maximum power of the PV array, it is faster and the voltage is stable.

Modeling and Simulation of Boost Converter with Voltage Feedback Control

In order to achieve a proper design and control, it is necessary to have an exact model of boost converter. In this paper, the mathematic model of boost converter is proposed by the state-space average method. In the next step, the open-loop transfer function model without compensation is deduced in detail according to the mathematic model of the boost converter, the controller is designed according to frequency domain. The phase margin and magnitude margin of the open-loop system of the boost converter with compensator have both been increased. After compensating, the control system becomes stable. Using Matlab 7.1, the simulation of the control system of boost converter was implemented. The simulation results of control system confirm that the controller can reduce steady state error and resist power supply disturbance.

A Precision and High-Speed Behavioral Simulation Method for Transient Response and Frequency Characteristics of Switching Converters

We propose a fast and precise transient response and frequency characteristics simulation method for switching converters. This method uses a behavioral simulation tool without using a SPICE-like analog simulator. The nonlinear operation of the circuit is considered, and the nonlinear function is realized by defining the nonlinear formula based on the circuit operation and by applying feedback. To assess the accuracy and simulation time of the proposed simulation method, we designed current-mode buck and boost converters and fabricated them using a 0.18-µm high-voltage CMOS process. The comparison in the transient response and frequency characteristics among SPICE, the proposed program on a behavioral simulation tool which we named NSTVR (New Simulation Tool for Voltage Regulators) and experiments of fabricated IC chips showed good agreement, while NSTVR was more than 22 times faster in transient response and 85 times faster in frequency characteristics than SPICE in CPU time in a boost converter simulation.
