Abstract

The invention discloses a single-transformer double-circuit type output converter, which comprises a high-frequency transformer, a switch 1, a switch 2, a switch 3, a switch 4, a quick-acting charging controller, a balance charging controller, a main control module, n batteries and n battery switches. Based on the above change of the circuit design, the high-frequency transformers of two original power supplies are integrated as one high-frequency transformer. During the voltage transformation switching process, two windings are separated from each other. Therefore, the structure of the above single-transformer double-circuit type output converter is reduced by the size of one transformer compared with the structures of two original single-circuit type transformers. As a result, the cost is reduced. The single-transformer double-circuit type output converter is reasonable in design and convenient to use.

Description

technical field [0001] In particular, the present invention relates to a single-transformer dual-channel type output conversion. Background technique [0002] At present, the charging combined with fast charging and balance charging mainly uses two switching power supplies to provide charging power. These two switching power supplies consist of two transformer structures. The main problem of the power supply structure composed of two independent switching power supplies is that the volume is relatively large and the cost is relatively high. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned deficiencies in the prior art, and provide a single-transformer dual-channel type output conversion. [0004] Technical scheme of the present invention is realized like this: [0005] A single-transformer dual-channel output conversion, including a high-frequency transformer, a switch 1, a switch 2, a switch 3, a switch 4, a fast ch...
