Get Started with Simscape Electrical

Model and simulate electronic, mechatronic, and electrical power systems

Simscape™ Electrical™ (formerly SimPowerSystems™ and SimElectronics®) provides component libraries for modeling and simulating electronic, mechatronic, and electrical power systems. It includes models of semiconductors, motors, and components for applications such as electromechanical actuation, smart grids, and renewable energy systems. You can use these components to evaluate analog circuit architectures, develop mechatronic systems with electric drives, and analyze the generation, conversion, transmission, and consumption of electrical power at the grid level.

Simscape Electrical helps you develop control systems and test system-level performance. You can parameterize your models using MATLAB® variables and expressions, and design control systems for electrical systems in Simulink®. You can integrate mechanical, hydraulic, thermal, and other physical systems into your model using components from the Simscape family of products. To deploy models to other simulation environments, including hardware-in-the-loop (HIL) systems, Simscape Electrical supports C-code generation.

Simscape Electrical was developed in collaboration with Hydro-Québec of Montreal.

Control DC Motor with PWM Voltage Source and H-Bridge Driver

Control DC Motor with PWM Voltage Source and H-Bridge Driver

Control a DC motor by using the Controlled PWM Voltage and H-Bridge blocks. The DC Motor block delivers a mechanical power of 10 W at 2500 rpm and turns at a no-load speed of 4000 rpm when the DC supply voltage is 12 V. Consequently, if you set the PWM reference voltage to its maximum value of 5 V, the motor runs at 4000 rpm. If you set the PWM reference voltage to 2.5 V, the motor runs at approximately 2000 rpm. To achieve fast simulation, this example sets the Simulation mode parameter of the Controlled PWM Voltage and H-Bridge blocks to Averaged. To validate the averaged behavior, set the Simulation mode parameter to PWM in both the Controlled PWM Voltage and H-Bridge blocks.

Model Triangle Wave Generator Using Operational Amplifiers

Model Triangle Wave Generator Using Operational Amplifiers

Model a triangle wave generator circuit by using two Band-Limited Op-Amp blocks. The first stage of the circuit represents a comparator constructed from an op-amp. Two Diode blocks model the Zener diodes that limit the output of the comparator to plus or minus 5 V. These limits result in a square wave.
