The communication directions such as transmission, router and automotive electronics, Aero-Space etc..There is design week due to setting up power-supply system using module
The features such as phase is short, reliability is high, system upgrade is easy, the application of power module is more and more extensive.Especially in recent years due to data
The continuous popularization developed rapidly with distributed power supply system of business, the amplification of power module is beyond primary power source.With
The a large amount of of semiconductor technology, encapsulation technology and high-frequency soft switch to use, power module power density is increasing, conversion efficiency
More and more higher, using also more and more simpler.
And the power module of high-power high-current output, in order to reduce output line pressure drop, it can typically carry " S voltage adjusting ends
Son ", that is, long-range regulating compensation terminal, i.e., be directly connected on the input port of load end in S+ terminals and S- terminals, to compensate
Power module is output to the line pressure drop of the input port of load end.
But if then common mode inductance can not be used in power module output stage, using " S pressure regulation terminal " because " S pressure regulation
The principle of terminal " is the input port from power module interior shifting to load by the output sampling end of power module, is so led to
The negative feed back control system crossed inside power module reaches voltage stabilizing purpose, and uses common mode inductance, equivalent in power output
On line and perceptual device is incorporated on signal sampling line, 90 degree of its current lagging voltage makes power output line and signal sampling line
Phase is asynchronous, is highly vulnerable to breakage the stabilization of degeneration factor, forms vibration.And power module then can not be very without using common mode inductance
Good suppression output noise, has used common mode inductance and has had larger line pressure drop without using " S pressure regulation terminal ", made load end
Brownout.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of common mode of power module

3. the utility model circuit is simple, easy to use.
The utility model is described in further details below with reference to drawings and Examples.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Reach technological means and effect that predetermined purpose is taken for the utility model is expanded on further, below in conjunction with accompanying drawing
And embodiment is to embodiment of the present utility model, architectural feature and its effect, describe in detail as follows.
A kind of circuit of the common mode inductance of power module, including the common mode inductance and S being connected with power module outlet
Each synchronous piece compensating line of coiling, the input and power supply of compensating line on pressure regulation terminal, the positive winding and negative winding of common mode inductance
Module output end is connected, the output end connection S pressure regulation terminals of compensating line.
Wherein, because compensating line is signal wire, not by high current, therefore compensating line of the present utility model is preferably thin
Line footpath wire rod；Compensating line is identical with the former lines Same Name of Ends of common mode inductance, and the number of turn and distribution are consistent.

Cause, distribution is consistent.Tetra- terminals of 1A, 2A, 3A, 4A are accessed to the signal sampling line of S pressure regulation terminals.RL is circuit load end.
Specifically, the utility model is each synchronous coiling one on the positive winding and negative winding of general common mode inductance
Line, the two lines of former common mode inductance also press primary circuit access power output line, the both threads access " S pressure regulation terminal " newly added
Signal sampling line, all introduces an equal amount of inductance equivalent on power output line and on signal sampling line, makes both
Phase synchronization, so as to avoid the vibration of degeneration factor.The compensating line of new synchronization coiling can select the wire rod of fine line diameter, but necessary
Identical with former lines Same Name of Ends, the number of turn is consistent, and distribution is consistent.
Common mode inductance circuit of the present utility model, makes the power module with High-current output can be same when using common mode inductance
When use S pressure regulation terminals；The utility model only need to each synchronous piece compensation of coiling on the positive winding and negative winding of common mode inductance
Line can connect S pressure regulation terminals, can't increase inductance volume；
The utility model circuit is simple, easy to use.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
