ES5340 interfaces when testing electric drives

ES5340-M

Powerful E-Motor and Inverter Simulation

The ETAS ES5340-M board measures the gate signals for the IGBTs (insulated-gate bipolar transistor) driven by the ECU, and stimulates its sensor signals for current, voltage, rotor speed, and position. Synchronization with the ECU’s PWM cycle (Pulse-width modulation) is realized either by an external synchronization signal or by clock recovery, i.e. automatic synchronization with the center-aligned PWM signals. The sensor signals for currents and voltages are represented as analog signals. Additional analog and digital signals such as error signals, temperature signals, or battery states are also available. Further digital or PWM signals can be measured, such as DC/DC converter triggers. All prevalent speed/position sensors such as resolver, sine encoder, or digital encoders can be represented. Other types of sensors or error signals can be simulated using powerful arbitrary signal generators.

Independence from the Model Step Size

With the current prediction method, developed by ETAS, the generation of current signals is supported by a hardware update rate of 1 MHz, independent of the step size of the simulation model running on the Real-Time PC.

Easy Enhancement

The slave board ES5340.1-S allows adding another six analog and six digital signal outputs. All output channels are synchronized with the master board by a fast data connection and can be driven by either a software model or the FGPA model.

ES5340-ICE

The ETAS ES5340-ICE board can be used to measure signals and generate arbitrary signals.

Measuring signals

There are 20 digital inputs available for measuring signals. The signals can be measured using a variety of time-based (cycle time, frequency, duty cycle, high time, etc.) and angle-based (additive high/low time, number of high/low pulses, etc.) methods.

Generating arbitrary signals

Eight freely programmable arbitrary signal generators are available, and these can be clocked by the central angle clock generator or by a local clock generator (0 - 1 MHz) for each signal generator. There are 16 signal banks available for all signal generators; during runtime it is possible to switch between them in real time.

Each signal generator has an internal or external voltage reference. There are digital and analog output modes. The output mode can be changed via software. Each output channel can be deactivated via software.

ETAS offers the LABCAR-MODEL-ICE simulation model for combustion engines.
