Ejemplos destacados
LC Transmission Line and Test Bridge
A transmission line model and bi-directional test bridge. Reflected and transmitted signals are slightly different if the test direction is changed. This is because the line model is not symmetric. This type of model can be used both to explore the impact of cable choice on transmission characteristics, and also to compare relative fidelity of different transmission line model structures and parameterizations.
Control de par motor directo de máquina asíncrona
Este ejemplo muestra cómo controlar una máquina asíncrona (ASM) con el método de control de par motor directo. Un controlador de velocidad basado en PI proporciona la referencia del par motor. El controlador de par motor directo genera los pulsos del inversor.
Three-Phase Asynchronous Direct Online Motor Connected to Hydraulic Pump
In this example, an asynchronous motor is connected to an ideal pump. The diameter of the valve on the hydraulic system affects the speed and current drawn by the motor.
Three-Phase Two-Level PWM Generator
Use the PWM Generator (Three-phase, Two-level) to control a Converter. The inputs to the PWM Generator are reference AC waveforms and a DC-link voltage of 400 V. There is one time scope for the controller waveforms.
Three-Phase Asynchronous Machine Starting
Model a wye-delta starting circuit for an induction machine. When the supply is connected to the machine via switch S1, switch S2 is initially off resulting in the machine being connected in a wye configuration. Once the machine is close to synchronous speed, switch S2 is operated thereby reconnecting the machine in a delta configuration. The higher impedance seen by the supply when the motor is in wye configuration reduces the starting current, and causes less disruption to other connected loads.
Earthing Effects with Unbalanced Load
The effects of three different types of earthing connections on network voltages and currents.
