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.
