Electronic Load Module
For the hardware-in-the-loop simulation of electrical machines, such as motors or generators, dSPACE offers the Electronic Load Module. The module is optimized for high-speed operation as required for simulating electric motors such as those in electric steering systems. It can work as both a current sink and a current source to provide bidirectional current flow, i.e., it generates or consumes real current on ECU motor outputs. The Electronic Load Module can be combined with the FPGA Base Board and the XSG Electric Library1) to provide the fast reaction times required for controlling electrical machines. The FPGA Base Board computes parts of the simulation model for the electrical machine, e.g., from XSG Electric Library, and operates the Electronic Load Module.
- Current sink and source capability
- High-speed current regulation ideal for loading PWM power stages
- Simulation of current ripple
- Different types of electric motors
- Remote-controlled by standard 10 V analog signals
The Electronic Load Module contains two independent load channels, which can control a unipolar current through its output stage. It provides high-speed current regulation of less than 5 µs. Each module can provide continuous current of 30 A and 300 W, and a maximum voltage of 30 V can be applied. Several modules can be connected in parallel to increase the current. Cooling is performed by a temperature-controlled fan. The modules are protected against overload and overtemperature. The control options can be configured via jumper switches. The two channels can be used as a sink and source device (bidirectional current) or they can be switched in parallel to double the maximum current if a current flow in only one direction is required. This expands the range of applications beyond electric motor simulation.
