These characteristics are achieved with the different control techniques for various microgrid model. Comparison Of DC-DC Boost Converters Using SIMULINK National Conference on 'Emerging Research Trends in Electrical, Electronics & Instrumentation' 36 Page (ERTEEI17) 2.2.1 Boost Converter A boost converter is a switch mode dc to dc converter in which the output voltage is greater than the input voltage. Rotary Institute of Chemical Technology Department of Electrical Engineering ADVANCED POWER ELECTONICS (2170906) TOPIC: Simulation of Boost Converter Using MATLAB SIMULINK. Some of the desired features of the inner-loop current control are as follows: (1) accurate current control (2) high bandwidth fast dynamic response, 4–6 times faster than that of the outer voltage controller (4) low current distortion, and filter resonance damping. Simulation of Boost Converter Using MATLAB SIMULINK. 1 v i dt CC C (8) The mathematical modeling approach includes graphical implementation method where data flow is drawn in Simulink platform. However, the quality can be improved by properly designing the controller and filter. which indicates the load voltage of the boost converter in case of ideal model. The inverter power quality can be influenced by the background network harmonics. Doing so saves a lot of time and it's much more easier as compared to the Buck. Each inverter is responsible for controlling its output current and power according to a power demand set by the supervisory controller. In this post, I am going to talk about modelling dc-dc power converters using MATLAB's user defined function block. The reference current is determined from the set values of the controller. 14) for the buck-boost converter and combined into a Simulink model block (Fig. The closed-loop controller ensures that the output current tracks the reference value with a zero steady-state error.įigure shows a block diagram of a grid-connected inverter control strategy, where the closed-loop current controller enables output power delivery by calculating an error signal from measured and commanded signals. Applying the same modeling techniques shown in the THD example in an effort to aid in optimization of power electronic converters and to exemplify the block modeling concepts discussed, the loss equations introduced in section 2.4 have been modeled in Simulink (Fig. The power set-points generate a current reference for the current regulator. The supervisory controller (SC), receiving power demand information from short-term/long-term prediction values, operates DG units either in a constant power output or in a load-following manner. The generated power is controlled by the in-phase current component which is proportional to the network power demand. The aim of the inverter is to export controllable power with the established voltage. In continuous conduction mode (current through the inductor never falls to zero), the theoretical transfer function of the boost converter is:
