This thesis presents two novel topologies of AC-DC converters with common neutral: five-level interleaved converter and five-level T type converter. Besides, a novel type of implementation of Indirect Current Control (ICC) is also presented. Thus, a comparative analysis of performance between three single phase AC-DC converters for UPS applications is realized. The analyzed converters have as common characteristics: power factor correction, digital control using FPGA and connection between input power supply and converter output enabling the use of UPS inverter and by-pass. The first one analyzed converter is the conventional three level converter which presents as main feature reduced numbers of power semiconductors and components. The sec...
