Analysis and Experimental Validation of Single-Phase Cascaded Boost AC–AC Converter with High Voltage Gain
Abstract
:1. Introduction
- A high-voltage-gain cascaded AC-to-AC boost converter is presented, which utilized low-voltage rating semiconductor devices and multiple cascaded boost units.
- The output voltage waveform was found to be a sine wave with low harmonics, and the robustness of the control system was confirmed through a case study in which a fault occurred at one unit.
- The control circuit’s ability to maintain the continuity of the output voltage after a fault occurs was confirmed.
- The proposed circuit was verified through both the simulated and experimental results, which demonstrated an excellent dynamic response with a continuous input current and a power factor close to unity.
