【摘要】 分析了三相四线制有源电力滤波器中逆变器的死区效应对其补偿性能的影响,研究了电流反馈控制和无死区控制两种补偿策略用于上述有源电力滤波器死区补偿的可行性,并通过仿真对两种方法的补偿效果进行比较。结果表明,两者均能有效补偿死区效应的影响;但在实现的难易程度和成本方面,无死区控制策略有一定优势。更多还原

【Abstract】 This paper analyzes the dead-time effects of the inverter in 3-phase 4-wire active power filter and its influence on the compensation performance of the APF.Study on the feasibility of adopting two kinds of dead-time effect compensation strategies-current feedback and no dead-time to the APF is also presented.The simulation results show that both strategies can compensate the influence effectively.However,the strategy of no dead-time provides certain superiority in the light of the complexity and cost.更多还原
