Custom Inductor (B-H Curve)
A comparison in behavior of a linear and nonlinear inductor. Starting with fundamental parameter values, the parameters for linear and nonlinear representations are derived. These parameters are then used in a Simscape™ model and the simulation outputs compared.
Custom Transformer (B-H Curve)
Calculation and confirmation of a nonlinear transformer core magnetization characteristic. Starting with fundamental parameter values, the core characteristic is derived. This is then used in a Simscape™ model of an example test circuit which can be used to plot the core magnetization characteristic on an oscilloscope. Model outputs are then compared to the known values.
Digital Potentiometer Parameterized from Datasheet
How to model a digital potentiometer such as is used to control audio amplifiers from a digital circuit or microprocessor-controlled system. The model also shows how you can create your own custom blocks in order to extend the Simscape™ Electrical™ library.
Electrical Transformer with Hysteresis
Model a custom transformer that exhibits hysteresis by using the Non Linear Reluctance block in a magnetic circuit. The transformer is rated for a 50W load and steps down from 120V to 12V rms. The magnetizing resistance Rm is modeled in the magnetic domain using an Eddy Loss block.
Frequency-Dependent Transmission Line
A custom frequency-dependent transmission line model. The characteristic admittance and propagation function are first derived from the frequency-dependent resistance, reactance, and susceptance. The derived values are fitted using RF Toolbox. The Universal Line Model (ULM) [1] is then implemented in Simscape based on the fitted parameters. The results from the frequency-dependent transmission line model and the classic pi-section transmission line model are compared.
Three-Phase Custom PMSM
A custom Simscape™ implementation of a Permanent Magnet Synchronous Machine (PMSM). To view the PMSM source code, double-click on the motor block and then click on the hyperlink 'Source code'. This test circuit shows the PMSM being used as a generator, the rectifier block converting the induced AC back EMFs to a DC voltage which is in turn applied to a resistive load.
Three-Phase Custom Simplified Synchronous Machine
How simplify the custom Simscape™ synchronous machine model.
Three-Phase Custom Synchronous Machine
A custom Simscape™ implementation of a Synchronous Machine (SM). To view the SM source code, double-click on the Synchronous Machine block and then click on the hyperlink 'Source code'.
Three-Phase Custom Transforms
A comparison of three-phase transforms.
Three-Phase Custom Zigzag Transformer
Two different ways to create a custom transformer component. The first uses built-in library blocks to lay out the magnetic circuit as a masked Simulink® subsystem. The second builds a custom Simscape™ component using the Simscape language.
개방 권선이 있는 4상 PMSM의 속도 제어
이 예제에서는 개방 권선이 있는 4상 PMSM(영구 자석 동기기)을 사용하는 전기-견인 드라이브의 회전자 각속도를 제어하는 방법을 보여줍니다. Open-End PMSM (Four-Phase) 블록의 소스 코드를 보려면 블록을 더블 클릭한 다음 설명 탭에서 '소스 코드' 하이퍼링크를 클릭합니다. DC 전압원이 2개의 제어된 4상 컨버터를 통해 PMSM에 전력을 공급합니다. PMSM은 부하에 따라 모터 모드와 발전기 모드 모두에서 작동합니다. 이상적 토크 소스가 부하를 제공합니다. Scopes 서브시스템은 시뮬레이션 결과를 확인할 수 있는 스코프를 포함합니다. Control 서브시스템은 바깥쪽의 각속도 제어 루프 1개와 안쪽의 전류 제어 루프 4개를 갖는 PI 기반 캐스케이드 제어 구조를 포함합니다. 1초의 시뮬레이션 중에 각속도 요구량은 0rpm, 500rpm, 2000rpm, 그런 다음 3000rpm입니다.
