Ejemplos destacados
Carga/descarga de batería de alta tensión
Este ejemplo muestra una batería de alta tensión como las que se utilizan en vehículos eléctricos híbridos. El modelo utiliza un perfil de corriente enlace de CC realista que se genera a partir de un ciclo de conducción dinámica. El tiempo total de la simulación es 3.600 s.
IPMSM Outer Loop Controller Evaluation
Control the rotor angular velocity in an interior permanent magnet synchronous machine (IPMSM) based electrical-traction drive. For evaluation of the outer loop velocity controller, the inner loop current controller is replaced by a three-phase controlled current source. An ideal torque source provides the load. The Scopes subsystem contains scopes that allow you to see the simulation results. The Control subsystem includes a PI-based outer loop controller. During the three-seconds simulation, the angular velocity demand is -1000, 2000, 3000, 4000, and then 5000 rpm.
Differential Pair Amplifier
A differential pair amplifier circuit. The circuit can be used to explore the properties of a differential pair amplifier. The model can be tested using differential and common-mode inputs. The balanced output has zero gain in common-mode provided that the two transistors have identical properties.
Solar Cell Power Curve
Generate the power-voltage curve for a solar array. Understanding the power-voltage curve is important for inverter design. Ideally the solar array would always be operating at peak power given the irradiance level and panel temperature.
Linear Voltage Regulator with Feedback
A simple voltage regulator circuit constructed from discrete components. A fluctuating supply is modeled as 20V DC plus a 1V sinusoidal variation. The zener diode D1 sets the non-inverting input of the op-amp to 3.2V, and hence as the op-amp has a large gain, the op-amp inverting input and output are also at 3.2V. Hence the regulator voltage output is regulated to be 3.2*(1000+470)/470=10V. The NPN bipolar transistor is required to provide higher currents than is possible from a typical op-amp. The model can be used to check circuit operation, and to support selection of components to achieve the desired voltage regulation.
