[Objective] The DC bus sampling method introduces additional harmonics into the phase current due to the use of pulse width modulation (PWM) phase shifting to compensate for the current reconstruction dead zone. To solve this problem, a phase current reconstruction scheme based on the multiple-branch sampling method was proposed. [Method] A theoretical analysis of the DC bus sampling method and the multiple-branch sampling method was conducted, focusing on the causes of the current reconstruction dead zone. Matlab/Simulink simulations were used for a comparative analysis of both methods. [Results] Simulation results indicated that the multiple-branch sampling method effectively avoided the dead zones in the low modulation index region and sector boundaries present in the DC current sampling method, reduced the harmonic content in the current, and enhanced the accuracy of current reconstruction. Experiments conducted at a motor speed of 60 r/min demonstrated that the maximum error in the reconstructed current was less than 0.5 A. [Conclusion] The experimental results verified the effectiveness and feasibility of the proposed multiple-branch sampling method for current reconstruction.
