| In this paper, a single-phase boost AC-AC converter with inherent commutation and step-changed frequency operation is proposed. Distinct from conventional AC-AC converters, the proposed design achieves output voltage regulation utilizing one high-frequency switch. The inherent commutation feature of the converter negates the necessity for additional snubber circuits or complex commutation strategies, thereby simplifying the control method for adjusting the output voltage amplitude and frequency. The continuous input current of the proposed converter eliminates the requirement for a bulky LC filter. A straightforward and adaptable switching strategy is implemented to produce output frequency variations. The approach of preventing the conduction of the body diode in power MOSFETs mitigates issues associated with poor reverse recovery, enabling high-speed switching. The operating principles of the converter are elucidated across various modes of operation, with key equations derived and analyzed. To substantiate the validity of the proposed design, simulation results obtained using PSCAD/EMTDC software at frequencies of 25Hz, 50Hz, and 100Hz are presented. | ||
