This test bench shows a proposal for 3-phase motor bridge driver. All half-bridges are connected in a star
configuration and drive a moror emulated with RL equivalent circuit. Each MOSFET is switched on and off at a
frequency of 20 KHz and a duty cycle of 40%. Each phase of one complete PWM pulse takes 3 ms. During this time,
each half bridge is switched 20 pulses one by the other in a complete rotation.
All half-bridges are configured to operate in sequencer mode with adaptive control enabled and middle values for
registers was chosen. For more details on the registers, please consult the data sheet and user manual.

Check in F11 command model parameters emulating internal registers and corresponding range of value. All numbers are in
decimal from 0 to maximum value depending on register bit size.

The simulation takes 3.5 minutes per each ms of transient simulation with 200ns maximum time step. The maximum
time step is required to have the correct accuracy of the gate current profile.
