Embodiment Construction
[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions of the present invention and the accompanying drawings.
[0028] The composition and structure of a bidirectional DC solid-state transformer with a high-frequency AC isolation link of the present invention is as follows: figure 1 shown. The bidirectional DC solid-state transformer is mainly composed of n identical DC converter units, n is a positive integer greater than or equal to 2; one port (low voltage end) of each DC converter unit is connected in parallel, and the other port of each DC converter unit One port (high voltage side) is serially connected in series.
[0029] The topology of each DC converter unit is a single-phase structure, including: two full-bridge converters H 1 、H 2 , an auxiliary inductor L, an isolation transformer T and two DC filter capacitors C 1 、C 2 , DC filter capacitor C 1 、C 2 respectively with the full-bridg...
