Abstract :
This paper deals with two solutions for single-phase serial AC voltage controllers with bipolar PWM chopper. In these converters, either the bipolar PWM AC matrix chopper (MC) based on full-bridge topology or the bipolar PWM AC matrix-reactance chopper (MRC) based on Cuk B2 topology and auxiliary transformer is applied. The MRC, in distinction to MC, has a magnitude of voltage transformation function greater than one. The peak detection method in the control circuit of both controller solutions is applied for fast control of the load voltage changes. The steady state theoretical analysis based on averaged models and transient state analysis based on small-signal averaged models of the presented controllers are employed. Furthermore, simulation and experimental test results are provided to confirm and verify the theoretical approach. On the basis of these investigations a comparative study of the results showing performance of both controller solutions is presented
