Co-simulation with Maxwell Technical Background

The co-simulation is the most accurate way of coupling the drive and the motor

model. The advantage of this method is the high accuraty, having the real

inverter currents as source in Maxwell and the back emf of the motor on the

inverter currents as source in Maxwell, and the back-emf of the motor on the

inverter side.

The transient-transient link enables the use to pass data between Simplorer and

Maxwell during the simulation:

Maxwell2D and Maxwell3D can be used

Simplorer and Maxwell will run altogether

Simplorer is the Master, Maxwell is the slave

At a given time step, the Winding currents and the Rotor angle are passed

from Simplorer to Maxwell, the Back EMF and the Torque are passed from

Maxwell to Simplorer

Insights on the coupling Method

The Simplorer time steps and the Maxwell time steps don’t have to be the

same. Usually, Simplorer requires much more time steps than Maxwell.

Assume the current simulation time is t

Simplorer, based on the previous time steps, gives a forward meeting time

t1to Maxwell where both simulators will exchange data. Between t0and t1,

both code run by themselves.

At t

1, both codes exchange data. If during the t0-t1period, some event

appears on Simplorer side (state graph transition, large change of the

pp p(g p,g g

dynamic of the circuit), Simplorer will roll back to t0and set a new forward meeting time t1’, t1’< t1.

Co-simulation with Maxwell Simplorer Schematic

We use a control signal for each igbt. IGBT1has the igbt1control signal (you

need to uncheck the use Pin button). Name the control signals of IGBT2to

IGBT6 accordingly.

Follow the naming as below

Co-simulation with Maxwell Simplorer Schematic

The reference waveforms are implemented using time functions: pick the Sine

Wave in the Basic Elements > Tools > Time Functions library.

Put 3 Sine Wave blocks on the schematic, with the parameters as above

Add a Triangular wave time function block

The switching of the IGBTs is done through a state graph that will compare the

reference wave forms and the chopper signal
