End ground connection, is connected with transmitting coil and matching capacitance between the second end of first switch pipe and the second end of second switch pipe altogether,
The method includes:
Step s11: close the voltage v2 at the second end of collection first switch pipe of having no progeny in first switch group；
Specifically, for convenience of description it is assumed here that first switch pipe, second switch pipe, the 3rd switching tube and the 4th are opened
Close d1, d2, d3 and d4 that pipe corresponds in Fig. 3 respectively, then first switch group is d1 and d4, and second switch group is d2 and d3.
Due to the afterflow effect of transmitting coil, close in first switch group and have no progeny, gather v2, to judge whether to turn on the
Two switches set.
Step s22: judge whether v2/v1 is less than preset value, if it is, entering step s23, otherwise, return to step
S11, wherein, v1 is the rated value of DC voltage；
Specifically, when v2/v1 is less than preset value, then illustrate that now v2 is sufficiently small, now control second switch group to lead
Logical is safe, and d3 can bear the electric current producing due to v2.Otherwise, step s11 and step s22 are repeated, until v2/v1
Less than preset value.
It should be noted that, although the afterflow effect of the distance of load range transmission coil and transmitting coil itself can make
V2 slowly reduces, but be also unlikely to make to turn on second switch group again when v2/v1 is less than preset value and lead to the full-bridge cannot be just
The often stage of work, namely this section of Dead Time do not interfere with the normal work of full-bridge.
Preferably, the scope of preset value is 10%-20%.
Preferably, preset value is 15%.
Certainly, the scope of preset value here and concrete numerical value can also be all other numerical value, and here of the present invention is not done
Special restriction, determines according to practical situation.
Step s23: control the conducting of second switch group.
When v2 drops to sufficiently small, control the conducting of second switch group, then, second switch group conducting Preset Time turns off again
Afterwards, then detect second switch pipe the second end voltage v3, judged using same method, so repeated, final ensured
The stable safe operation of full-bridge circuit.
Preferably, step s11 also includes:
Close the actual value v0 of collection DC voltage of having no progeny in first switch group；
Then step s22 is:
Judge whether v2/v0 is less than preset value, if it is, entering step s23, otherwise, return to step s11.
It is understood that although DC voltage should be specified constant in theory, because can be subject in practical application
To the interference of place environment, lead to the fluctuation of DC voltage, therefore, in order to improve control accuracy further and then improve full-bridge electricity
The security performance on road, the application is closing the actual value v0 of collection DC voltage of having no progeny in first switch group, by the ratio of v2 and v0
Value is being judged.
Preferably, the process closing the actual value v0 of collection DC voltage of having no progeny in first switch group is:
The actual value v0 of collection DC voltage while gathering the voltage v2 at the second end of first switch pipe.
In order to improve the security performance of control accuracy and then raising full-bridge circuit further, can be in collection first switch pipe
The voltage v2 at the second end while collection DC voltage actual value v0.
To sum up, the present invention can be according to the change in voltage of specified point come the dutycycle of accommodation switching tube, even if negative
Also the stable safe and reliable operation of full-bridge circuit is ensure that in the case of load is uncertain.
The invention provides a kind of full-bridge guard method, including closing the of collection first switch pipe of having no progeny in first switch group
The voltage v2 at two ends；Judge that whether v2/v1 is less than preset value, if it is, controlling the conducting of second switch group, otherwise, repeat on
State process, wherein, v1 is the rated value of DC voltage.It can be seen that, the present invention first switch group close have no progeny can't immediately or
Turn on second switch group after fixing Dead Time, but judge voltage v2 and the unidirectional current at the second end of first switch pipe
Whether the ratio of the rated value of pressure is less than preset value, only when being, just controls the conducting of second switch group, substantially reduces the 3rd
The presence due to voltage v2 that undertakes during switching tube conducting and the electric current that produces, improve the security performance of full-bridge, stability and
Reliability.
