Welding Inverter Design Calculator
Wired White v1 Size a two-switch forward welding inverter: transformer turns and copper, output choke, switch currents and losses, mains demand, and the arc load characteristic.

Off-Grid Solar System Sizing Calculator
Wired White v1 Size an off-grid solar array, battery bank, MPPT or PWM controller and inverter from daily loads, sunless days and worst-month peak sun hours.
PWM Simulator: SPWM, SVPWM and Discontinuous PWM
Wired White v1 Compare SPWM, SVPWM, THIPWM and DPWM0–3. Animate the space-vector hexagon, inspect seven-segment switching and dwell times, and compare current ripple and relative switching loss.
