Description

The Cycler block implements an ideal galvanostat, potentiostat, or a cycler.

To configure this block as a galvanostat, set the Configuration parameter to Galvanostat, specify current. The Cycler block then represents an ideal current source or sink that is powerful enough to maintain the specified current through it regardless of the voltage across it. The output current is the value at the physical signal port, i.

To configure this block as a potentiostat, set the Configuration parameter to Potentiostat, specify voltage. The Cycler block then represents an ideal voltage source that is powerful enough to maintain the specified voltage at its output regardless of the current passing through it. The output voltage is the value at the physical signal port, v.

To configure this block as a cycler, set the Configuration parameter to Cycler, specify current or voltage. When the value at the control physical signal port, c, is equal to 0, the cycler turns off. When the value at the control physical signal port, c, is equal to 1, this block represents a galvanostat. When the value at the control physical signal port, c, is equal to 2, this block represents a potentiostat.

This table shows the overall behavior of the Cycler block:
