Abstract

The invention discloses a circuit structure allowing energy to flow bidirectionally. According to the circuit structure allowing the energy to flow bidirectionally, a switch tube part is formed by parallel connection of a switch tube and a diode. The circuit structure allowing the energy to flow bidirectionally comprises a DC / DC conversion part, a DC / AC conversion part and a filtering part, wherein the DC / DC conversion part is connected with a power supply and a first capacitor, the first capacitor is connected with the ground, the DC / AC conversion part is connected with the first capacitor and the filtering part, and the filtering part is connected with an output end. According to the circuit structure allowing the energy to flow bidirectionally, AC inversion can be conducted when the energy flows in the forward direction, DC chopping can be conducted when the energy flows in the reverse direction, quite high conversion efficiency is achieved, and quite high flexibility of circuit design is achieved.

Description

technical field [0001] The invention relates to the field of circuit topology, in particular to a circuit structure with bidirectional flow of energy. Background technique [0002] A common circuit combination structure BOOST+Fullbridge at this stage, because of the unidirectional conductivity of the main diode D1 of the previous stage BOOST, can only realize DC / AC energy conversion, but cannot realize AC / DC conversion. limitations of use. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and provide a circuit structure in which energy flows bidirectionally. The present invention realizes AC inversion when energy flows forward, and DC chopping when energy flows reversely. And achieve higher conversion efficiency and circuit design flexibility. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realiz...
