“…In [40], an adaptive dead-time compensation method based on sixth harmonic elimination is proposed. In order to improve the performance of the control algorithm, the method uses an adaptive harmonic filter to suppress the sixth harmonic.…”

“…It is known that, due to the influence of dead-time, the output current contains harmonics. A method named the current harmonic filter method calculates the compensation voltage by filtering the sixth current harmonic in the d-q synchronous rotating coordinate system [40,41]. The output current of the grid-tied inverter contains odd-numbered harmonics because of dead-time and nonlinear characteristics of the switching devices.…”

“…A novel method of compensating for dead-time effects, which uses a feed-forward approach for the standard compensation and a feedback loop with adaptive harmonic compensator to suppress the persistent sixth harmonic components in the d-q axis current, is presented in [40]. This method does not rely on parameter calculation.…”

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.

In order to reduce the vibration and noise of permanent magnet synchronous motors, this paper proposes a control strategy by analyzing the relationship between the vibration and noise of the permanent magnet synchronous motor and the current harmonics of the inverter based on actual project applications. Some methods include random switching frequency modulation technology, random pulse position modulation technology and dead zone compensation technology on current harmonics are analyzed respectively in this paper. Then this paper proposed a mixed control strategy, which combined with random switching frequency-random and pulse position-dead zone compensation methods. Matlab tools are used to simulation and verification the Mixed control strategy. Simulation and experimental results show that this control strategy can effectively reduce the total underwater noise level of permanent magnet synchronous motors.
