T4 is arranged and the first inductance L1, the value of the second inductance L2, the equivalent diode in the first switch S1 in Dead Time t3-t4
Conducting, it is achieved that no-voltage (Zero Voltage Switching, the ZVS) conducting of the first switch S1, as shown in Figure 3.
(2) when the first switch S1 conducting, when second switch S2, the 3rd switch S3 turn off, the first port 101 gives the first inductance
L1 charges, and simultaneously gives the second inductance L2 charging through the first electric capacity C1, and transmits energy to the second port 102, the 3rd electric capacity C3 to
3rd port 103 transmits energy.When first switchs S1 shutdown moment, the dead band that second switch S2, the 3rd switch S3 not yet turn on
In time t1-t2, the electric current on the second inductance L2 flows to the second port 102 from the contact B of the first electric capacity C1 and the 3rd switch S3,
Electric current on first inductance L1 from the first inductance L1 and first switch S1 contact A place flow to ground or in the opposite direction flow but
Current value is less than the current value (the electric current afterflow on the first inductance L1, the second inductance L2) on the second inductance L2, by reasonably
Dead Time t1-t2 is arranged and the first inductance L1, the value of the second inductance L2, in Dead Time t1-t2 in second switch S2
Equivalent diode, the 3rd switch S3 in equivalent diode be both turned on, it is achieved second switch S2, the 3rd switch S3 ZVS lead
Logical, as illustrated in figures 4-5.

Turn on situation for ZVS during output port, use the ZVS conducting situation of other input/output port can be deduced accordingly, herein
Repeat no more.
By the first inductance L1, the voltage-second balance of the second inductance L2, the output voltage of the second port 102, the 3rd port 103
Output voltage and the relation of input voltage of the first port 101 as follows, as shown in Figure 6:
Wherein VinIt is the input voltage of the first port 101, VC2It is the output voltage of the second port 102, VC3It it is the 3rd port
The output voltage of 103, D is the conducting dutycycle of the first switch S1.
At the first port 101 as the input port of DC-DC converter, the second port 102 and the 3rd port 103 are DC-
During the output port of DC changer, in the case of underloading, whole switching tube S1-S3 the most easily realize ZVS conducting, under case of heavy load,
First switch S1 ZVS relatively difficult to achieve conducting, but appropriate design the first inductance L1, the second inductance L2 parameter and DC-can be passed through
The output of DC changer, thus obtain from zero load to the fully loaded DC-DC converter being Sofe Switch.
Second port 102 is identical with the 3rd port 103 voltage magnitude, opposite polarity；Second port the 102, the 3rd port 103
Can carry out buck relative to the first port 101, first port the 101, second port 102 polarity is identical.When first switch S1,
Second switch S2 is active switch pipe, and the 3rd switch S3 is active switch pipe, coordinates the first switch S1, second switch S2 and the 3rd
The driving signal of switch S3, it is possible to achieve the arbitrarily ZVS conducting of whole switching devices during flow of power direction.
Through emulation testing, the present embodiment is capable of between three port 101-103 any flow of power direction, and all
Switching tube realizes ZVS conducting；Through experiment test, when the first port 101 being set to the input port of DC-DC converter, second
