To prevent short-circuits between the upper and lower switches of power converters from over-current protection, the dead time is mandatory in the switching gating signal for voltage source converters. However, this results in many negative effects on system operations, such as output voltage and current distortions (e.g., increased level of fifth and seventh harmonics), zero-current-clamping phenomenon, and output fundamental-frequency voltage reduction. Many solutions have been presented to cope with this problem. First, the dead-time effect is analyzed by taking into account factors such as the zero-clamping phenomenon, voltage drops on diodes and transistors, and the parameters of inverter loads, as well as the parasitic nature of semiconductor switches. Second, the state-of-the-art dead-time compensation algorithms are presented in this paper. Third, the advantages and disadvantages of existing algorithms are discussed, together with the future trends of dead-time compensation algorithms. This article provides a complete scenario of dead-time compensation with control strategies for voltage source converters for researchers to identify suitable solutions based on demand and application.

The paper considers the problem of parameter identification of the surface mounted permanent magnet synchronous motor (SPMSM) with pulse width modulated (PWM) inverter in the presence of dead time of power switches and other nonlinear distortions. Parameter identification of the SPMSM is required for the tuning of the torque control loop, because in some cases, the exact values of phase resistances and inductances are not known. In the absence of nonlinear disturbances, the problem of SPMSM parameters estimation is not difficult. The influence of the dead-time effect, back electromotive force and measurements noise introduces distortions in experimental output data sets, which leads to incorrect parameter estimation. Thus, there is a need to develop new designs of identification experiments and methods of processing of the experimental data. A detailed mathematical model of SPMSM with a PWM inverter in the presence of dead-time effect is considered in the paper. The negative influence of the dead-time effect on the results of parameter estimation is shown. A modified technique of parameter identification of SPMSM based on the estimation of frequency response function is proposed. The applied design of identification experiments, the type of excitation input signal, and methods of data processing allow us to minimize the influence of nonlinear disturbances and to reduce the variance of estimation of frequency response function. These features provide a high performance of SPMSM parameters estimation.

“…Considering the non-linear characteristics of the inverter and the existence of air gap magnetic field distortion, the three-phase voltage and current waveforms of the motor will be distorted. Numerous current harmonics also appear in the stator, of which 5th, 7th, 11th, and 13th order current harmonics are dominant [25]- [27]. Considering the four aforementioned dominant current harmonic components of phase current and voltage, the current formula of i a , i b , i c in Fig.…”

In order to solve the problem of torque ripple caused by current harmonic of induction motors (IMs) in electric vehicles (EVs) drive system, this paper presents a novel control method in the feedback channel based on morphological filters (MFs) to suppress the current harmonics. First, an analytical model of current harmonics is established, and the current harmonic composition to be filtered in the feedback channel of motor control systems is provided. Second, on the basis of filtering requirements on the feedback channel and the basic idea of mathematical morphology, a hybrid digital MF is designed. The MF is subsequently added on the current loop to suppress the current harmonic components. The shape, width and height of the structural elements of the filter are optimized by parameters comparison methods to improve the performance of the filter in harmonic suppression. Finally, compared with the method based on Butterworth Filter and without filters, simulation and experimental results verify the feasibility and effectiveness of the proposed method for suppressing harmonics.
