If the Breaker block happens to be in series

with an inductive circuit, an open circuit or a current

source, you must use a snubber.

2.Parameters:

Snubber resistance Rs_The snubber resistance, in ohms (). Set the

Snubber resistance Rs parameter to inf to

eliminate the snubber from the model.

Snubber capacitance Cs_The snubber capacitance, in farads (F). Set

the Snubber capacitance Cs parameter to 0

to eliminate the snubber, or to inf to get a resistive

snubber.

3.Limitations

When the block is connected in series with an inductor or another

current source, you must add the snubber

circuit.

In most applications you can use a resistive snubber (Snubber

capacitance parameter set to inf) with a large resistor value (Snubber resistance parameter set to

1e6 or so).

Because of modeling constraints, the internal breaker inductance

Ron cannot be set to 0.

You must use a stiff integration algorithm to simulate circuits

with the Breaker block. ode23tb or ode15s

with default parameters usually gives the best simulation

speed.
