New features and changes introduced in this version are organized by these topics:
New features and changes introduced in this version are:
The Actuators & Drivers library now contains blocks for modeling piezoelectric travelling wave motors. The library contains these new blocks:
The Piezo Rotary Motor models the torque-speed characteristics of a rotary piezoelectric motor.
The Piezo Linear Motor models the force-speed characteristics of a linear piezoelectric motor.
The H-Bridge block now provides the option to dissipate current via two freewheeling diodes when the signal at the PWM port is low. To use this new option, select Via two freewheeling diodes for the Freewheeling mode parameter.
New features and changes introduced in this version are:
The Passive Devices library now contains Current-Controlled Switch and Voltage-Controlled Switch blocks to model electrical switches with hysteresis.
The Passive Devices library now contains a Resistor block to model a resistor as a function of temperature and process data.
The Passive Devices library now contains a Crystal block to model the electrical characteristics of a crystal resonator.
The Variable Inductor and Variable Capacitor blocks have the following enhancements:
The Variable Inductor block now provides two options for the relationship between the voltage across the device and the current through the inductor. The new Equation parameter lets you select the voltage-current equation that you want.
The Variable Capacitor block now provides two options for the relationship between the current through the device and the voltage across the capacitor. The new Equation parameter lets you select the current-voltage equation that you want.
New features and changes introduced in this version are:
The Solar Cell block has the following enhancements:
The block now provides the option to use an 8-parameter model that includes an additional diode and a parallel resistor.
The block now models temperature dependence.
The SPICE-Compatible Sources library (in the Sources library) contains blocks for modeling dependent sources with two controlling inputs. The library contains these new blocks:
PCCCS2 — Model polynomial current-controlled current source with two controlling inputs
PCCVS2 — Model polynomial current-controlled voltage source with two controlling inputs
PVCCS2 — Model polynomial voltage-controlled current source with two controlling inputs
PVCVS2 — Model polynomial voltage-controlled voltage source with two controlling inputs
New features and changes introduced in this version are:
The NMOS and PMOS blocks now provide the option to model the electrical characteristics of SPICE Level-3 MOSFET devices.
