Reference design for reinforced isolation 3-phase inverter with current, voltage and temp protection

This design provides a reference solution for a three-phase inverter rated up to 10kW, designed using the reinforced isolated gate driver UCC21530, reinforced isolated amplifiers AMC1301 and AMC1311, and MCU TMS320F28027. Lower system cost is achieved by using the AMC1301 to measure motor current (...)

Junction temperature vs. PCB copper coverage area
These are estimated power dissipation and thermal results.
Care must be taken to ensure that device junction temperature
does not exeed the maximum ratings as indicated in the datasheet.

This calculator uses the PCB copper area to estimate the device junction temperature. See notes on usage and calculation method.
