1. With up to three 7 kVA inverters per phase, the 3-phase system sizes are 21, 42 or 64 kVA. In the example in Figure 2 with a 60 kVA source and load, there is approximately 87 Aac per phase. This means that at least two inverters per phase would be required as each inverter can pass through up to 50 amps.
Solution A single 3-phase autotransformer can be used to step down the incoming 277V per phase (480V 3-phase) to 230V per phase for the GS7048E AC inputs. The 230V inverter outputs are then stepped up through another 3-phase autotransformer to 277V per phase (480V 3-phase).
The output of an inverter control MCU is 3.3-V PWM signal. This has to be converted into a 10-mA current signal. Multiple circuit configurations can be implemented for this conversion. TIDA-010025 has provisions on board to evaluate each of the input drive methods.
