Description
Technical field
The present invention relates to a kind of integrated dual input current transformer of the DC-AC-DC of realization energy transformation, relate in particular to three port DC/DC converters of the integrated dual input of a kind of current source type full-bridge converter and series resonant converter.This converter utilizes the current mode full-bridge converter to realize the high frequency square wave inversion in input dc power stream source; Adopt series resonant converter to realize the high frequency sinusoidal current conversion of input voltage source, utilize the transformer of many windings to realize the dual input three port DC/DC converters that the coupling isolation of input side high frequency square wave electric current and sinusoidal current is transmitted.
Background technology
Along with constantly popularizing of new forms of energy product; Emerged in large numbers a large amount of topological structures that is applicable to the clean energy resource power supply; Wherein the multiport converter gains great popularity because of himself unique characteristic; Because different energy form, energy storage device and loads has different voltages with different grade and voltage-current characteristic, so these equipment can not directly link together.The multiport converter connects input source, memory device and load with a concentration power processing unit, makes that control is more convenient, has reduced cost, and can obtain maximum energy from each new forms of energy.
The topology of existing multiport converter can be divided into non-isolation type circuit, half isolated form circuit and full isolated form circuit three major types, and the elementary cell of composition multiport converter has voltage-type and current mode two big classes.People concentrate on the topology of being made up of the voltage-type elementary cell mostly for the research of multiport converter; But when forming the multiport converter owing to the voltage-type elementary cell, the voltage clamp effect owing to Transformer Winding often causes two ports to influence each other to the process of load transmission of power.The change in voltage of a port generally can have influence on the operate as normal of another port.And for the current mode input translator,, can't realize the transmitted in both directions of power because the topology that adopts is an electric current one-way flow structure.
Utilize new energy, constitute the novel power grid structure, become a kind of trend.And new forms of energy ubiquity power density inhomogeneous with shortcomings such as the voltage magnitude excursion is big; If adopt the topology of voltage-type multiport converter as power converter; Certainly will need to introduce more complicated control mode, remedy voltage magnitude and change the influence that causes.
