| Abstract |
The paper presents a multi-purpose AC-AC power converter with thyristors applying the principles of soft-switching. The proposed converter operates with a high-internal frequency of about 10 kHz applying low-cost and efficient thyristor switches. On objective is to improve the technology of polyphase AC converters with controllable four-quadrant operation. The main content is the control of the external waveforms by means of a non-uniform and a periodic sampling process. By simplifying the various modes of transfer of electrical energy through the converter, a simple and practical solution for the digital control electronics for a high-frequency AC-AC converter is realized. A resonant six-switch and twelve-switch DC-AC and AC-AC power converter topology is implemented. Results from simulation and experiment are presented. |
