AMC1100: Ground reference for 3 Phase Current sensing

TIDA-010025: Three phase inverter sensing parameters and reference code

Part Number: TIDA-010025
Other Parts Discussed in Thread: TIDA-00366,

Hi, I was designing a 3 phase inverter(750VA) for a three phase 500W motor load application.  I found some TI reference designs TIDA-010025 and TIDA-00366, which are designed for the same application. However, I noticed that in these designs only the output current and the DC bus voltage are monitored.

 1. Why is the output line voltage not being sensed? How is the control logic implemented without measuring the output voltages?

2. I searched extensively for the firmware/code for TIDA-00366 and TIDA-010025, but it has not been published anywhere. Is there any possible way to get it and start my program?
