For this week’s QSPICE schematic capture, we have a “Bidirectional 3-phase 4-leg Inverter” by our friend Arief Noor Rahman. “My simulation is mostly focused on control and transient performance. Unlike how I see most people’s simulation so far, I simulate the detailed controller interrupt algorithm and it includes the startup and protection. It helped me to make hardware testing to be very predictable. in the simulation, you can also try to apply more load current, and the circuit will have internal OCP fault triggered and stop the all the PWM. This fault is latched and can only be resetted by send ZERO on_off signal.” (Schematic Capture Post #037) To access the project files, please go to: QSPICE/3phase 4leg inverter at main · physicboy/QSPICE · GitHub.
