一种具有反相和同相操作且无换流问题的新型Buck-Boost AC-AC变换器

This paper proposes a new type of ac-ac converter which can operate as traditional noninverting buck and boost converters, and inverting buck-boost converter as well. The proposed converter uses six unidirectional current flowing and bidirectional voltage blocking switches, implemented by six reverse blocking insulated-gate bipolar transistors (IGBTs) or series mosfet-diode pairs, two input and ou...
