AI Technical Summary
Existing AC-AC converters suffer from high switching losses, low efficiency, and complex control during the high-frequency conversion process. In particular, single-stage converters are more complex to control, and existing technologies struggle to achieve simple and efficient conversion from low-frequency to high-frequency electricity.
A single-phase high-frequency AC-AC converter is adopted, which utilizes the input resonant network and the load impedance matching network to achieve zero-voltage switching through a bidirectional power switch S, reducing the DC link and the number of switches. The structure is simple and the control is relatively simplified.
It achieves the conversion from low-frequency electricity to high-frequency electricity, reduces switching losses, improves system efficiency, and simplifies the control process.
