一种具有固有换流和变频运行能力的高频隔离四开关单相准Z源AC-AC变换器

In this article, a high-frequency isolated single-phase quasi-Z-source ac–ac converter is proposed. This converter can generate a broad range of output voltage while also allowing the output frequency to be changed. The configuration is divided into two similar subcircuits in a way that only one unidirectional switch exists in each subcircuit, and complementary switches are removed. Therefore, the...
