Abstract
The invention provides a power converter. The power converter comprises a first chopper unit, a resonance unit and a second chopper unit, which are successively connected. The resonance unit comprises three groups of resonance inductors, three groups of resonant capacitors and transformers subunits. Each of the transformer subunits comprises three first windings and three second windings. Each group of the resonance capacitors and one group of the resonance inductors are serially connected to form a serially connection branch. Three serially connected branches formed by three groups of the resonance capacitors and three groups of resonance inductors are connected in a triangular manner, so a first angle-shaped branch is formed. In the first angle-shaped branch, a wiring node of every two serially connected branches is connected with a first end of one first winding of the corresponding transformer subunit. Second ends of the three first windings of each transformer subunit are connected with the first chopper unit. The three second windings of each transformer subunit are connected with the second chopper unit. According to the invention, compared with the prior art, the type of devices can be quite easily chosen and the devices are quite easily achieved.
Description
technical field [0001] The invention relates to the technical field of power electronics, in particular to a power converter. Background technique [0002] Power converters such as resonant converters have been widely used in various fields due to their high efficiency. A multi-phase resonant converter is disclosed in the Chinese patent "Multiphase Resonant Converter and Its Controlling Method" with application number 201010261397.1, which includes a first chopping unit, a resonant unit and a second chopping unit , see the specific structure figure 1 shown. Among them, the resonant unit includes three sets of resonant inductors, three sets of resonant capacitors and transformer subunits, each set of resonant inductors, a primary winding of the transformer subunit, and a set of resonant capacitors are connected in series to form a branch circuit, three sets of resonant inductors, three sets of resonant The three branches formed by the capacitor and the three primary windin...
