The PFC controller provides current shaping of the AC input and regulates the DC bus. Four ports non-isolated DC-DC converter block diagram. After making the Simulink model and connecting to dSPACE to send the suitable pulse to the transistor of the converter, the DC motor starts working by applying the DC voltage to the converter. The skeleton diagram of such a multiport converter that is going to be modeled in Matlab/Simulink environment is given in Fig. motor, two DC-DC converters (Boost and Buck) are tested using two different switches (GaN and SiC transistors). The duty cycle of the PWM output determines the amount of boost imparted to the input voltage. an uninsulated DC-DC multiport converter with for ports. For simplicity, only one phase has been used for the boost operation. In order to do so, select edit data/ports under tools as shown in fig. The DC-DC boost converter on the kit has a two-phase interleaved topology. Now we want the parameters be set as variables so that the user can change them. VL = Vg - (Vo*dbar) - iL*((Ron*D) + RL) % Inductor voltage IC = (iL*dbar) - iout % Capacitor current Vo = vC + Resr*((iL*dbar) - iout) % Output voltage

The code should look something as follow: The 5 inputs via mux are stored in an array format. The above equations can be entered directly to our MATLAB function. Over one switching period, the equations can be combined and represented as follow: Similarly, when MOSFET switches off, the equations are When the MOSFET is on, the behavior of the converter can be captured by the following equations, This video demonstrates the design and simulation of the Boost Converter / DC-DC Step-Up Converter using MATLAB/Simulink. You can refer to the boost converter post to get an in-depth view of how these equations are derived. Going back to the user defined function, this is where we will enter the converter state equations. 5: Setting parameters in repeating sequence block Generate C or HDL code from circuit models to a real-time target computer for validating a controller using hardware-in-the-loop simulation.Fig.Generate C or HDL code from control algorithms for rapid prototyping using a real-time target computer or for implementing them on a microcontroller or FPGA.Evaluate boost converter power quality by simulating it as part of a larger system where a DC-DC power converter is one of the components-for example, digital power supply or a grid-connected PV array.Model and assess the impact of component tolerances and fault events on the operation of a switching power supply.Design gain-scheduled controllers to account for operating point variations.
