Interactive Generation of MOSFET Characteristics
Explore the impact of parameter choices on the I-V and C-V characteristics for a surface-potential-based MOSFET model. To open the MOSFET Characteristics window, in the MATLAB® Command Window, type MOSFETParameterAnalyzer.
Control de tensión del convertidor Buck
Este ejemplo muestra cómo controlar la tensión de salida de un convertidor Buck. Para ajustar el ciclo de trabajo, el subsistema Control utiliza un algoritmo de control basado en PI. La tensión de entrada se considera constante a lo largo de la simulación. Una resistencia variable proporciona la carga para el sistema. El tiempo total de la simulación (t) es 0,25 segundos. En el instante t= 0,15 segundos, la carga cambia.
Four-Quadrant Chopper Control
Control a four-quadrant chopper. The Control subsystem implements a simple PI-based control algorithm for controlling the output current. The simulation uses both positive and negative references. The total simulation time (t) is 1 second. At t = 0.5 seconds, the polarity of the load DC source E is changed.
Composite Three-Phase Rectifier
This is the base model for analysis workflow examples.
Buck Converter
Model a switching power supply that converts a 30V DC supply into a regulated 15V DC supply. Use this model to size the inductance L and the smoothing capacitor C and to design the feedback controller. Select between continuous and discrete controllers to explore the impact of the discretization.
Marine Full Electric Propulsion Power System
A representative marine half-ship electrical power system with base load, hotel load, bow thrusters and electric propulsion.
Power Converter Model Fidelity Comparison
Use different levels of fidelity in power converters. You change the level of fidelity by changing the values for the Fidelity level, Switching device, and Integral protection diode parameters of the Converter (Three-Phase) block. You also change the inputs to the G port. Using a higher level of fidelity improves the accuracy of the results but it also slows down simulation.
Three-Phase Matrix Converter
A three-phase matrix converter that drives a static load and draws unity power factor at the source. The Scopes subsystem contains scopes that allow you to see the simulation results.
Surge Protection in Buck Converter
How a varistor may be applied to a buck converter in order to protect the switching MOSFETs from over-voltages due to a differential surge.
Inverting Topology Buck-Boost Converter Control
Control the output voltage of an inverting topology buck-boost converter. The inverting topology buck-boost converter uses only a single switch and the output voltage is of the opposite polarity than the input. To adjust the duty cycle, the Control subsystem uses a PI-based control algorithm. The input voltage and the system load are considered constant throughout the simulation. The total simulation time (t) is 0.25 seconds. At t = 0.15 seconds, the voltage reference changes and the system switches from buck mode to boost mode.
Implement Power Factor Correction for CCM Boost Converter
Correct the power factor using a PFC pre-converter. This technique is useful when non-linear impedances, such as switch mode power supplies, connect to an AC grid. As the current flowing through the inductor is never zero during the switching cycle, the boost converter operates in continuous conduction mode (CCM). The inductor current and the output voltage profiles are controlled using proportional-integral control. During start up, the reference output voltage is ramped up to the desired voltage.
