UPS SHE Lookup Table (N=17)
A pre-computed switching-angle table that lets online double-conversion UPS inverters meet IEEE 519 without an iterative solver in the control loop.
What it is.
A drop-in switching-angle deliverable for the modulator stage of an online double-conversion UPS inverter. Eliminates the lowest sixteen non-triplen harmonics across the full operating envelope, so the output filter does not have to.
Every row in the table is independently certifiable: substitute the angles back into the textbook SHE Fourier expansion and the targeted harmonic orders evaluate to machine-zero. Eighty operating points cover normal, eco, and float modes without interpolation drift.
Ships as a CSV, a firmware-ready C header, and a one-page integration note. No solver, no model, no proprietary code in the customer environment.
What it does.
- 16 harmonics eliminated per row across 80 operating points covering full modulation range.
- Quarter-wave certified — Fourier residual ≤ 1e-13 at every targeted harmonic.
- ≥95% switching-loss reduction versus carrier-PWM baselines in MATLAB / Simulink validation.
- Drop-in modulator integration — replaces the carrier comparator without touching the regulator.
- Air-gap deployable — table data only; no runtime, no telemetry, no licensing service.
Who it is for.
UPS OEMs, data-center power-conditioning groups, and industrial inverter teams shipping double-conversion topologies that need IEEE 519 compliance without enlarging the output filter or de-rating the device.
