Converters, inverter-based resources, VFDs, relays & ladder logic.
4 concepts
DC-to-AC conversion: PWM and modulation index, output voltage formulas, grid-following vs grid-forming inverters, and IEEE 1547 ride-through basics.

Convert AC to DC: diode and SCR behavior, half-wave, full-wave, and six-pulse outputs, firing-angle control, ripple, and the harmonics rectifiers inject.

Control induction motor speed with a VFD: constant V/f flux control, the rectifier-bus-inverter chain, drive harmonics and mitigation, and braking options.
