Description |
 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. |
 NMosfet |
Enhancement mode NMOSFET transistor, modeled for typical
switching operations, i.e. when Vgs>Vgsth, the transistor
conducts between its drain and source. |
 PMosfet |
Depleted mode PMOSFET transistor, modeled for typical switching
operations, i.e. when Vgs<Vgsth, the transistor conducts between
its drain and source. This transistor is complementary to the
enhancement mode NMOSFET, i.e. it conducts when Vgs is very
small. |
 Diode |
A model of a typical diode with the knee voltage and conducting
mode differential resistance. The diode can be used as a passive
single quadrant switch, conducting positive on-state currents and
blocking negative off-state voltages. Note: the model does not
include reverse recovery losses yet, this will be implemented in
the future. |
 GateDriver |
A gate driver ensures that a high switching signal is converted
into the proper gate to source voltage, ensuring that the signal
will actually switch the MOSFET transistor to ON or OFF state. The
gate driver should be connected as follows: dp - PWM modulator's
positive pin dn - PWM modualtor's negative pin gp - MOSFET's gate
pin tn - MOSFET's source pin |
 SingleQuadrantSwitch |
A single quadrant switch, conductiong positive on-state
currents and blocking positive off-state voltages. The switch is
implemented as an enhancement mode NMOSFET transistor with a gate
driver included. |
 CurrentBidirectionalSwitch |
A current bidirectional two quadrant switch, conducting
positive or negative on-state currents and blocking positive
off-state voltages. The switch is implemented using an enhancement
mode NMOSFET transistor and a diode, connected in parallel. A gate
driver for the transistor is included. |
 VoltageBidirectionalSwitch |
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. |
 FourQuadrantSwitch |
A four quadrant switch, conducting positive or negative
on-state currents and blocking positive or negative off-state
voltages. The switch is implemented as a pair of two voltage
biderectional switches, connected in paralel and in opposite
directions. Both transistors and diodes are identitcal. Gate driver
for the transistors are included. |
