Information

General

This component simulates the behaviour of an h-bridge using ideal switches.

Implementation

This model has 4 ideal switches Q1, Q2, Q3 and Q4 wich their respective diode. Q1 and Q4 form half bridge and Q2 and Q3 the other half bridge.
The bridge is controlled using a Sign-Magnitude drive with boolean inputs and outputs.

Notes

• The voltage should be applied on the electrical interfaces (Vpos and Vneg) using an external dc source for example DCSource .
• It uses the Sign-Magnitude method to control the signal SignMagnitudDrive .
• The motor pins should be connected to the MotorA and MotorB pins.
• The inputs are the logical inputs PWM and ENABLE (or direction), which can be generated by an external element, for example Controller .
• This model has a voltage sensor (real value) between MotorA and MotorB pins and
• Ron (switch resistance when ON) and Goff (swithch conductance when OFF) can be zero.
