Gate driving
As mentioned previously, gate driving of the switches is performed through the latest L6390
family of devices. Refer to
dead time insertion. A fault signal is also fed back to the J5 connector if an overcurrent is
detected.
Amplifying network
The voltages across the three shunt resistors are amplified by K to correctly condition the
current feedback signals and optimize the output voltage range for a given phase current
range and A/D converter input dynamics. Refer to
on how to dimension the op-amp conditioning network depending on your needs.
Brake feature
The brake feature performs a motor brake by switching simultaneously to the low side power
MOSFET, thus shortening the motor phases.
Temperature feedback
Temperature feedback is performed by way of an NTC. It enables you to monitor the power
stage temperature so as to prevent any damage to the inverter caused by over temperature.
Warning:
This feature is mandatory in applications that require the
motor to operate in a flux-weakening region. In these
conditions, the back-EMF generated by the rotor’s spinning is
greater than the bus voltage and the brake feature prevents
the motor from acting as a generator destructively charging
the bus capacitance. Refer to
information.
