Pipe.DC/DC conversion electric powers circuit is by connecting DC/DC drive control circuits, DC output rectifier and filters and in main transformer pressure
On device increase an auxiliary winding NS2, on the main output loop of main transformer connect DC main switch circuits formed.
Charger OBC main switch circuits are for LLC circuits, phase whole-bridging circuit, PWM half-bridges or full-bridge or by cascade voltage stabilizing electricity
Road forms.
DC main switches are connected on the main winding of main transformer, DC main switches, which are connected to, to be paid on the winding of side circuit.I.e.
The DC main switches on transformer main winding are connected to not instead of with the directly parallel connection of the rectifying tube of its main output loop, are connected
Different location on paying side circuit winding, to meet the different type of pre- regulator circuit.
DC/DC conversion electric power circuits further include pre- regulator circuit, pre- regulator circuit respectively with DC main switch circuits and output
Filtering and protection circuit are connected.
As shown in Fig. 2, if pre- regulator circuit is BOOST circuits, DC main switches are connected to charger and pay side winding
The outside in circuit, the i.e. one end umber of turn N3.
Conversely, as shown in figure 3, if pre- regulator circuit is BUCK circuits, DC main switches need to be connected to charger pair
The inside of side winding loop, the i.e. exit of umber of turn N3.
As shown in figure 4, if stepping functions may be implemented in pre- regulator circuit, i.e., pre- regulator circuit is BUCK-BOOST electricity
Road.Output rectification circuit includes rectifying tube, and DC output rectifier and filters are connected with auxiliary winding NS2, and DC main switch circuits can
Think push-pull circuit, half-bridge circuit or full-bridge circuit.DC main switches are in parallel with rectifying tube.
For the power battery of low-voltage power supply, pre- voltage stabilizing is suitble to use BOOST circuits, is improved with sharp overall efficiency.For height
Voltage lithium electricity is proper with the pre- equalizing networks of BUCK.Specifically can according to selected DC main circuits type and the type selecting of switching device come
Consider.
In BUCK cascade circuits short-circuit effect can be formed for the idle winding induced voltage in the same side when DC being avoided to work
Fruit needs in addition to add an electronic switch, sees the K42 of Fig. 2, "Off" state is in when DC works, when charger works

The outside in group circuit is connected.
Inductance L1 in Fig. 2~Fig. 4 as the outputting inductance of charger, can both can also be used as the pre- voltage stabilizing electricity of DC
Sense.
Further include passing through with the CAN main MCU controlled and CAN interface circuit, charger rectifying and wave-filtering and main switch circuit

Afterwards, as soon as can be completed to dock with vehicle communication system with CAN communication port, this saves the hardware resource of communication.Principle
Upper CAN controller and interface circuit can be placed on pair side of DC, i.e. low voltage output loop side, and avoiding problems CAN ports
Insulation request.For convenient CAN Functional Designs, a main MCU controlled with CAN, the voltage of other earth-return circuits may be used
Current sample and control can be managed and be controlled with sub- MCU, can be isolated communicating between each MCU with serial ports, physical circuit shows
Meaning is as shown in Figure 5.
The present invention main improvement be connected to OBC pay sides DC switching devices be not with rectifying tube directly it is in parallel, i.e.,
It is a kind of two sections of windings for having tap to draw to pay side winding, and the advantages of designing in this way is can be according to the upper and lower of OBC output voltages
Limit range pays side turn ratio the original of the parts main transformer DC is adjusted flexibly, to coordinate the design of the pre- voltage stabilization part of DC primes.I.e.:
Since either BUCK or BOOST circuits, the voltage of pre- voltage stabilizing output all unidirectionally change relative to input voltage, and
OBC originals pay side the turn ratio in order to meet in charger state while can provide low voltage DC output (its no-load voltage ratio design be opposite
It is fixed).The OBC of main transformer pay while and DC pay while the number of turns design be substantially stationary.It is big in power battery voltage change
Range fluctuates and low-voltage output loses under the harsh conditions of the full dual variation of electricity, the pre- regulator circuit of DC single-stages either BUCK circuits
Or BOOST circuits are all difficult to fully meet the target call of consolidation circuit.
Other than the DC schemes of above tap design, pre- voltage stabilizing grade can also meet above-mentioned want using buck topological circuit
It asks, only the transfer efficiency of step-up/step-down circuit will be less than BUCK or BOOST circuits, and cost can also improve, can be high-power etc.
Fig. 4 is shown in using this scheme under specified conditions.
The present invention can merge CAN communication port, that is, use the MCU of a piece of band CAN control functions can be complete
All built-in functions of pairs of consolidation circuit are managed and external communication.In view of high pressure primary side and charger pay side and DC pairs
There are three the internal detection analog quantity of linear optical coupling transmission isolator, may be used or directly make distributing pipe with several small single sheets on side
It manages and carries out isolation communication using the serial ports end of chip, see Fig. 5.
As shown in fig. 6, by taking one exports the charger of charging voltage 72V as an example, DC output voltage V2 is set as 13.8V,
Charger output voltage range is between 60-90V.
In view of output voltage is 72V cell grades, DC uses the pre- regulator circuits of BUCK.To improve the efficiency of DC conversions,
Generally take umber of turns of the 1T as 13.8V.For covering power battery end 60V lower limits, N2=3T is taken, then reflected voltage is about
(13.8+1) * 3=45V, pre- voltage stabilizing maximum duty cycle about 75%, category compare reasonable interval.
For OBC main circuits are half-bridge circuits, winding NP needs to meet in terminal voltage about 180V (it is assumed that PFC is exported
400V, the pre- voltage stabilizing maximum duty cycle of charger main circuit 90%), when DC output end voltage about 15V, then NP=180/15=12T,
The number of turns that charger exports winding is about NS=90*12/180=6T.In view of DC primary side windings have been determined as 3T, therefore need to lead
Transformer adds the winding of a 3T that can meet requiring for charger pair side output voltage again.
Operation principle:The pre- regulator circuits of BUCK are constituted by switching tube K46, diode D36, inductance L16, pwm signal is by PWM
Controller provides.A pair of full pulse width signal driving switch pipe K16 and switching tube K26 of controller output simultaneously completes push-pull circuit work
Make.
Voltage can be induced when working in view of N2 on N1, to avoid short circuit from accessing switching tube K36, when DC works
It is driven by MCU and completes switching.
Diode D46, diode D56 and capacitance C46 constitute the rectifying and wave-filtering of low tension loop, export the work(of 13.8V/40A
Rate.
Half-bridge circuit is constituted by switching tube KP16, switching tube KP26, capacitance C16 and capacitance C2 6, if front end UP comes
It is exported from adjustable pre- voltage stabilizing, then switching tube KP16, switching tube KP26 can be operated in full pulsewidth and realize ZVS.If front end
It is not voltage stabilizing output or fixed constant pressure output (PFC outputs), then KP16, KP26 need to be operated under PWM mode.The main electricity of charger
Road can also be realized with full-bridge or push-pull circuit.
Design principle and parameter using BOOST circuits as the scheme of the pre- voltage stabilizings of DC its transformer is determined with more than
BOOST is similar.Its difference lies in need to consider when power battery voltage is high-end, that is, the above case 90V when determine DC master
Then circuit primary side the number of turns determines that OBC's pays side the number of turns, finally determines the number of turns and structure of transformer by the above process again.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
