Abstract Dead-time exists in the active power filters. By using the influence parameter of dead-time effect, this paper carries on the quantitative simulation analysis of dead-time in fundamental component and harmonic domain. Combining the application experience, three methods of dead-time compensation are discussed in this paper, including no dead time switch mode, novel current feedback dead time compensation method and dead time pre-compensation method. Simulation and experimental results show the efficiency of thses methods.

Key words： Dead-time effect switch mode current feedback pulse-width modulation harmonic region active power filter
