modelVoltageBidirectionalSwitch

A voltage bidirectional two quadrant switch, conducting positive on-state currents and blocking positive or negative off-state voltages. The switch is implemented using an enhancement mode NMOSFET transistor and a diode, connected in series. A gate driver for the transistor is included.

Extends from ActiveSwitchAb ( An abstract model that defines pins, common to all active switches, derived from this model. Typically 'ctrl', relative to 'gnd', will determine whether the connection between 'p' and 'n' is opened or closed. Current from/to 'ctrl' will typically be negligible. ).
