This paper presents a passivity-based control (PBC) design methodology for three-phase voltage source inverters (VSI) for uninterruptable power supply (UPS) systems where reduced harmonic distortions for the nonlinear load. reduced output voltage overshoot. and a restricted settling time are required. The output filter design and modification for efficient control and existing challen... https://www.roneverhart.com/Clear-Zig-Zag-Pet-Gate/
