Three-phase inverter reference design for VAC drives
This reference design from TI realises a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. The UCC23513 gate driver used has a six-pin wide body package with optical LED emulated inputs which enables its use as pin-to-pin replacement to existing opto-isolated gate drivers.
This design shows that the UCC23513 input stage can be driven using all existing configurations used to drive opto-isolated gate drivers.
In-phase shunt resistor based motor current sensing is done using AMC1300B isolated amplifier and DC link voltage, IGBT module temperature sensing using the AMC1311 isolated amplifier. The design uses a C2000 LaunchPad for inverter control.
