Abstract :
In this paper, structures of PWM AC power controller circuits with “dead time” control are presented. Theoretical analysis results of the basic electrical properties of simplified circuit models, especially taking in account the quality of power conversion are presented. Some test results obtained during laboratory model investigations of selected three-phase PWM AC power controller circuits are also proposed in this paper
