“…Permanent magnet synchronous motors (PMSMs) are widely used in industry because of their high power density and reliable performance [1][2][3]. Due to the less power switching devices, the three-phase four-switch (TPFS) inverter has become an alternative to the conventional three-phase six-switch (TPSS) inverter in cost-sensitive or fault-tolerant PMSM applications [4][5][6]. Therefore, the TPFS inverter-fed PMSM drive system has received considerable attention in recent decades.…”

This paper proposes a capacitor voltage offset suppression method based on reference voltage self-correction for a three-phase four-switch (TPFS) inverter-fed permanent magnet synchronous motor (PMSM) drive system to improve the motor control performance. Firstly, the αβ-axis reference voltage deviation caused by capacitor voltage offset is analyzed, and the relationship between the voltage to be compensated and the offset is obtained. Then, the capacitor voltage offset is calculated according to the motor speed, rotor position, current vector amplitude, and capacitance on the capacitor bridge arm of the TPFS inverter. Finally, the reference voltage is corrected according to the voltage to be compensated and the capacitor voltage offset. This method is simple and easy to implement, and there is no need to add voltage sensors or filters in the system to extract the capacitor voltage offset, and there is no complex parameter adjustment. The effectiveness of the proposed method is verified by experiments on a 20 kW interior permanent magnet synchronous motor.

“…It is a cost effective solution replacing the (TPSS-VSI) because of the ease of its control structure and reduced complexity [3] . For IPMSM drive systems, MPCC is an emerging control strategy [4,5] , which adopts the principle of model predictive control (MPC). MPC strategies have the ability to deal with system constraints, multi-objective optimization and multivariable control problems, and have been widely used in the control of power electronic converters.…”

In this study, a novel model-predictive-current-control (MPCC) is developed and implemented based on an interior permanent magnet synchronous motor(IPMSM) drives fed by threephase four-switch voltage-source inverter (TPFS-VSI) with fewer switches and lower costs. Compared with the conventional MPCC method, the complicated weighting factors designing process is avoided and it can greatly reduce the d-q axes currents and three-phase current ripples. Finally, MATLAB/Simulink simulation results validate the effectiveness of the proposed method .

“…However, the cost, volume, and weight are increased, which are limited in the EV applications. Three-phase and four-switch inverters (3P4SIs) [9] can realize the switch open-circuit fault-tolerant control without increasing the cost, volume, and weight, and thus, it has outstanding advantages in the field of EVs. After an open-circuit fault is detected and located with the fault-detection strategy [10,11], the four normal switches continue to work by connecting the dc bus midpoint to the faulty phase with bidirectional thyristors.…”

A switching sequence model predictive direct torque control (MPDTC) of IPMSMs for EVs in switch open-circuit fault-tolerant mode is studied in this paper. Instead of selecting one space vector from the possible four space vectors, the proposed MPDTC method selects an optimized switching sequence from two well-designed switching sequences, including three space vectors, according to a new designed cost function of which the control objectives have been transferred to the dq-axes components of the stator flux-linkage under the maximum-torque-per-ampere control. The calculation method of the durations of the adopted space vectors in the optimized switching sequence is studied to realize the stator flux-linkage reference tracking. In addition, the capacitor voltage balance method, by injecting a dc offset to the current of fault phase, is given. Compared with the conventional MPDTC method, the complicated weighting factors designing process is avoided and the electromagnetic torque ripples can be greatly suppressed. The experimental results prove the effectiveness and advantages of the proposed scheme.
