In accordance with some embodiments, a buck-boost circuit is contemplated which is bi-directional. That is, the buck-boost circuit be configured to produce a load voltage for a load responsive to a source voltage from a voltage source, and the buck-boost circuit may also be configured to pr...
This paper provides a theoretical analysis of the circuit. The circuit has six operating modes when the energy storage inductorLdccurrent is interrupted. The operating modes Ⅰ, Ⅱ, and Ⅴ are positive half-cycles, and Ⅲ, Ⅳ, and Ⅵ are negative half-cycles. Due to the special structure of...
