Abstract

The invention discloses a programmable non-isolated DC-DC converter topology search method. The method comprises the following steps of dividing a non-isolated DC-DC converter into a first structure,a second structure and a third structure; setting the type and number of devices contained in the second structure, and performing structure initialization on the second structure to generate a network table H; performing first condition screening on the network table H of the second structure to generate a network table G; combining the first structure, the third structure and the screened secondstructure network table G to obtain a network table F; and screening the network table F by using a second condition to generate all feasible topological network tables E. According to the method, topology search can be carried out on the non-isolated DC-DC converter, and the function of searching the topology of the non-isolated DC-DC converter in a computer program mode is achieved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a programmable non-isolated DC-DC converter topology search method. Background technique [0002] Non-isolated DC-DC converters play an important role in various applications such as new energy power generation, data center power systems, satellite power systems, and consumer electronics. In the face of increasingly complex application fields, traditional Buck, Boost and other converters are difficult to meet future needs, so it is necessary to explore new DC-DC converters. [0003] At present, there are several ways to propose new non-isolated DC-DC converters: (1) By using basic structures such as switched capacitors, switched inductors, and voltage doubler units to construct new topologies, but this method Although it can realize the construction of multiple topologies, it is difficult to achieve new breakthroughs with several basic structures; (2) relying on practi...
