  • Description: <jats:title>Abstract</jats:title><jats:p>This paper presents a new space phasor modulation (SPM) scheme for the operation of the H‐bridge multicell inverter under fault conditions. The topology of this inverter consists of several single‐phase H‐bridge inverters which can be independently bypassed if a fault is detected. As this action may result in an asymmetrical inverter topology, a new method based on the SPM is proposed to avoid voltage unbalances. Simulations and experimental results obtained in a five‐level multicell inverter prototype validate the proposed fault‐tolerant method. Copyright © 2007 John Wiley &amp; Sons, Ltd.</jats:p>
