Description
Technical field
It the utility model is related to a kind of converter circuit, it is specifically a kind of to be self-regulated with bi-directional synchronization rectification and dead band
Converter circuit.
Background technology
For DC/DC converters as the conversion for realizing different DC voltages, general traditional DC/DC converters are unidirectional conversion
And the DC/DC conversion of non-isolated BUCK-BOOST topologys.Now to meet energy storage, the energy makes full use of.Vehicle-mounted and,
In terms of Battery formation, there is an urgent need to traditional non-isolation type DC/DC converters, due to not possessing electricity for DC/DC two-way changings
Gas is isolated in secure context and hidden danger be present, therefore isolated form DC/DC reversible transducers turn into main study subject.
The most preferential with LLC topologys in DC/DC converters, LLC topologys have almost that gamut interior energy realizes ZVS, and in f
＜ fr (resonant frequency) secondary rectifying tubes can realize ZCS, and its control mode is PFM, tremble frequency pattern as born, can improve electricity
The EMC on road.It is unidirectional diode rectification mode if Fig. 1 is conventional full bridge LLCDC/DC converters.
As shown in Fig. 2 it is LLCDC/DC transducer synchronous rectifications.Traditional diode rectification, exported in low-voltage, high-current
In the case of, the ratio that the conduction loss of diode accounts for is big so that circuit efficiency is difficult to adjust, and the increase of loss brings radiating again
Difficulty adds radiating cost, it is necessary to increase corresponding cooling measure, and modularization volume is also difficult to do small, and reduces circuit
Reliability, while do not realize the function of DC/DC two-way changings.
DC/DC converters can then reduce the conduction loss that rectifying tube is brought, improve circuit effect according to synchronous rectification
Rate, radiating cost reduce, and circuit power density can also do height, while can also realize DC/DC two-way changing functions.
LLCDC/DC transducer synchronous rectifications, it brings some problems such as in f ＜ fr, and P ＜ Po (rated power)
Under the conditions of, synchronous rectification can bring current flowing backwards problem.Current flowing backwards problem can make it that secondary pipe occurs when turning off
Vds spikes stress and the increase of secondary turn-off power loss, while cause primary side by body diode current feedback coupled to primary side, it is former
The Reverse recovery of side pipe body diode is likely to result in primary side instantaneous short circuit, and this may cause primary side damaged tubular.This is significantly
Circuit reliability is reduced, counnter attack irrigation technology must be realized.Fig. 2 is in general LLCDC/DC synchronous rectification letter compositions.
Secondary Q5-Q8 driving is voltage between the Vds that respective tubes are detected by synchronous rectification IC, by between Vds
Voltage ratio relatively controls Q5-Q8 driving.It can only realize unidirectional DC/DC conversion, can not realize DC/DC two-way changings, and
In the presence of being possible to not realize ZVS Sofe Switch under high pressure underloading or low pressure heavy duty, this is relevant with the setting of dead time.
Mostly used for traditional LLC-DC/DC conversion and determine Power MOSFET, but for LLC, it is in low pressure
Heavy duty with high pressure underloading in the case of, it is required realize ZVS Sofe Switch time phase difference it is big, depend merely on determine dead time probably can not meet
Sofe Switch in real gamut, while determine dead time to a certain extent and have impact on circuit efficiency.
As shown in figure 3, being LLCDC/DC transducer synchronous rectifications and dead band regulation scheme, the program is entered to LLC circuits
The regulation in dead band is gone, it is realized ZVS in gamut, while realize synchronous rectification counnter attack filling.But its using
DSP algorithm is by carrying out dead band regulation in the presence of secondary power output and switching frequency f.
This can only realize DC/DC monotonic transformation functions, and the regulation in dead band is controlled using DSP, increase the complexity of control
Property, especially become in the two-way DC/DC of progress and change, it is more complicated.
