Information

General

This component simulates the behaviour of an h-bridge using MOSFET transistors.

Implementation

This model has 4 transistors Q1, Q2, Q3 and Q4 wich their respective diode. Q1 and Q4 form half bridge and Q2 and Q3 the other half bridge.
Q1 and Q3 are PMOS transistors while Q2 and Q4 are NMOS given the configuration.
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
• The transconductance of transistors can be change.
