In this paper, two different structures of a multiphase inverter for controlling a Brushless DC (BLDC) motor are presented and compared parameters These two structures are in fault mode. In the first structure, each phase of the BLDC motor is fed from an individual H-Bridge inverter, which is controlled by a Proportional-Resonance (PR) controller. The system dealt with in this paper is designed especially for reliability-critical applications. In other words, the motor structure has to be implemented not to compromise the drive performance even in fault conditions. For these purposes, modular designs to minimize the coupling between each phase. in the second structure, a typical six-legged inverter is used, which is divided into two groups of three phases with double Y-connected windings displaced by 30 degrees is presented and switching is done using Space Vector Pulse Width Modulation (SVPWM). According to the model, the use of SVPWM modulation for a six-phase motor reduces computations. MATLAB/Simulink software has been used to analyze these two structures and the results of its simulations are given.
