摘要：
A subsection integrated deed-time effect suppression strategy is presented in this paper to suppress current harmonic distortion caused by deed-time effect in voltage source inverter. On one hand, deed-time is eliminated by controlling only one bridge leg according to stator current direction of motor in nonzero current zone, meanwhile the voltage error caused by conduction voltage drop and switch delay is corrected. On the other hand, nonlinear error caused by zero current clamping effect is decreased by equivalent time compensation method based on pulse in zero current zone. Furthermore, in order to maximally eliminate the deed-time, an optimal switch method of the proposed PWM strategies is designed. The simulation and experimental results show the reduction of total harmonic distortion(THD) of stator current and the suppression of the influence caused by deed-time on the system, which demonstrates the validity and practicability of the proposed method. © 2018, Harbin University of Science and Technology Publication.
