Problems solved by technology

However, the resonant converter in the prior art can only unilaterally convert DC to AC or AC to DC, which also makes it impossible to switch freely in the conversion of DC and AC. The external circuit under the existing module makes the conversion efficiency of the resonant converter low and the heat loss high, which in turn makes the power supply too large and inconvenient to move and carry

Abstract

The invention provides a bidirectional symmetrical resonant converter, and relates to the technical field of resonant converters. Comprising an alternating current-to-direct current control module, a first resonance adjustment module, a transformer L3, a second resonance adjustment module and a direct current-to-alternating current control module, the output end of the AC-DC control module is connected with the input end of the transformer L3 through the first resonance adjustment module. The output end of the transformer L3 is connected with the input end of the direct-to-alternating current control module through the second resonance adjusting module; and the input end of the alternating current-direct current control module is connected with the output end of the direct current-alternating current control module. According to the resonant converter, free conversion between direct current and alternating current can be achieved, the problems of low conversion efficiency and high heat loss of the resonant converter caused by an external circuit are avoided, the size of a power supply connected with the resonant converter is reduced due to reduction of energy consumption, and the convenience of movement and carrying is improved.

Description

technical field [0001] The present invention relates to the technical field of resonant converters, in particular to a bidirectional symmetrical resonant converter. Background technique [0002] Inverters have a variety of uses in power supplies, including the generation of AC power, such as when used as inverters to convert DC output voltages to AC power (eg, uninterruptible power supplies). However, the resonant converter in the prior art can only unilaterally convert DC to AC or AC to DC, which also makes it impossible to switch at will in the conversion between DC and AC. In order to achieve the purpose of switching, it is necessary to The existing module has an external circuit, so that the conversion efficiency of the resonant converter is relatively low, and the heat loss is relatively high, thereby making the power supply bulky and inconvenient to move and transport. Therefore, there is a need for a resonant converter that can switch between alternating current and ...
