Space-Vector PWM Inverter & Motor Drive (2D)
Interactive 2D simulator of a three-phase space-vector PWM inverter driving an induction motor: watch the rotating reference vector step through the six-vector switching hexagon, the stator winding excite phase by phase, and a live oscilloscope trace the duty-cycle split, while the rotor spins at synchronous speed under V/f control.
Every variable-frequency motor drive — from an EV traction inverter to a factory pump VFD — works by chopping a fixed DC bus voltage into a synthetic three-phase AC waveform using space-vector PWM. This 2D simulator renders the real six-vector switching hexagon that an SVPWM algorithm steps through, a stator winding that lights up phase by phase as the reference vector rotates, an induction-motor rotor that spins at the resulting synchronous speed, and a live oscilloscope tracing both the phase voltages and the instantaneous duty-cycle split. Adjust fundamental frequency, DC bus voltage and modulation index — or lock them together with V/f control the way a real drive protects its motor from magnetic saturation — and watch live readouts track the active switching sector, the vector angle, peak phase voltage, synchronous speed and the d1/d2/d0 duty split.
