Space‐vector pulse‐width modulation (SVPWM) and carrier‐based PWM (CBPWM) of eight‐switch three‐phase inverters (ESTPIs) which are the post‐fault reconfigured topologies for the three‐level neutral‐point‐clamped inverter with an open‐circuit fault in a leg are introduced. On the basis of the PWM regular sampling method, the modulating functions of CBPWM which are equivalent to SVPWM of ESTPIs are derived, therefore the relationship between SVPWM and CBPWM of ESTPIs is revealed. The validity of the theoretical analysis is verified by experimental results.
