Specific embodiment
Below by specific embodiment combination attached drawing, invention is further described in detail.Wherein different embodiments
Middle similar component uses associated similar element numbers.In the following embodiments, many datail descriptions be in order to
The application is better understood.However, those skilled in the art can recognize without lifting an eyebrow, part of feature
It is dispensed, or can be substituted by other elements, material, method in varied situations.
The present invention is described in detail below in conjunction with drawings and examples.
Converting Unit of the invention provides current in middle wire circuit in such a way that split capacitor is combined with middle line bridge arm,
And system cost is reduced using the mode that SiC-MOSFET is combined with Si-IGBT, while proposing middle line bridge arm and other
The decoupling control method of three-phase gives the feasibility that middle line bridge arm uses Si-IGBT to complete.
It is as shown in Figure 1 the vehicle-mounted two-way charger centerline construction of electric car proposed by the invention, mainly by two
Divide and constitutes: double active bridges (Dual Active Bridge, DAB), by switching tube S1~S8Composition；Transformer primary side and secondary side
The turn ratio is set as 1:N, and N is determined by the alternating voltage that batteries of electric automobile voltage is exported with three-phase；Three-phase four-line dc-to-ac converter (3-
Phase 4-Wire Inverter, 3P4W-inverter) by three traditional bridge arm Sa1~Sc2, bus split capacitor CN1, CN2
And middle line bridge arm Sn1, Sn2It constitutes.Output filtering uses LC filter, it may be assumed that La, Lb, Lc and Ca, Cb, Cc, the value is by system
The parameters such as switching frequency, output power, THD determine.
The control method of the vehicle-mounted two-way charger centerline construction of electric car proposed by the invention is: when the part DAB is former
When the phase of Pulse Width Modulation (PWM) control signal is ahead of secondary when pwm signal, energy is by electric car
User is flowed to, realizes that the discharging function of V2H, V2G or Vs2Vs mode, corresponding 3P4W-inverter use Sinusoidal
Pulse Width Modulation (SPWM) completes control.When the phase of primary side pwm control signal lags behind secondary side pwm signal
When, energy flows to electric car by power grid, realizes the charge function of G2V mode.To meet the needs of client, by split capacitor
(CN1,CN2) and middle line bridge arm (Sn1,Sn2) constitute unbalanced load when current in middle wire circuit.When unbalanced load occurs,
The oscillation of split capacitor, the middle line bridge arm and other three-phases can be effectively suppressed using pwm signal control middle line bridge arm
Switching frequency is in 1:4~6 (preferably 1:5)) ratio work, the control of the middle line bridge arm can be full decoupled with other three-phases,
Keep system control more easy.
Middle line bridge arm design and analysis:
For the stabilization for ensuring N voltage in midpoint under unbalanced load, it is necessary to which rationally control middle line bridge arm makes most of middle line electricity
Stream flows through inductance Ln, and split capacitor voltage is avoided to shake.Simultaneously because most of current in middle wire is no longer flow through split capacitor,
Its capacitance can significantly reduce, and can save the weight, volume and cost of system.
The topology middle line bridge arm equivalent model is similar to the one phase equivalent model of three-phase inverter, equivalent model such as Fig. 2
It is shown, wherein Cequ=CN1+CN2For equivalent capacity, LNFor middle line inductance, RNFor the series equivalent internal resistance of middle line inductance, RvFor void
Quasi- active damping resistance.If Fig. 3 is the middle line bridge arm Bode diagram under voltage control loop, the gain of resonance point is by middle line inductance Ln
With the equivalent capacity C in equivalent circuitequWhat resonance generated.To make to improve middle line bridge arm to the control speed of split capacitor voltage,
The ability of dynamic response is improved, simple and easy method is that current control inner ring is added.
The design controls middle line bridge arm using lower frequency switching speed.But in practical applications, since number is controlled
The presence of system control delay processed, it is necessary at low frequency for the stability of different control deferred verification systems.In this middle line
Bridge arm switching speed is 10kHz, other threephase switch frequencies are 50kHz, and in conjunction with active damping, middle line bridge arm control system is not
It is as shown in Figure 4 with Bode diagram when control delay N.
Referring to fig. 4: when control is delayed N >=3, close to 180 °, system plays pendulum its cross-over frequency.And in N
When=1, phase margin is about 30 °, can guarantee that system is safely and steadily run.And in control frequency in 10kHz, number
Word control delay can guarantee in 1.5 bats, it may be assumed that can guarantee N≤1.It therefore, can be steady when middle line bridge arm working frequency is 10kHz
The fixed effective control for completing alignment voltage.As shown in figure 5, mid-point voltage is inclined under difference switching frequency when electric current loop is added
Move control effect analogous diagram.
Fig. 5 shows the dynamic process that mid-point voltage is adjusted under different middle line bridge arm switching frequencies.In setting initial voltage
When offset is 60v, no matter switching speed uses 50kHz or 10kHz, and unbalance of neutral-point voltage can be adjusted near 0V.When not
When balanced load occurs, the adjustable neutral point deviation voltage of the switching speed of 50kHz and 10kHz to 5V or less.And as seen from the figure:
When either initial biggish voltage deviation or unbalanced load occur, the controller when current feedback is added has comparatively fast
Regulating power.Therefore, the dynamic response and stability of system can be effectively improved into control system by current feedback being added.When not
In the presence of balanced load, three-phase and four-line inversion system each section simulation waveform is as shown in Figures 6 and 7.
From Fig. 6 and Fig. 7: when unbalanced load occurs and does not enable mid-point voltage control strategy, mid-point voltage is had
Biggish offset is followed by shaking for the alternating voltage same frequency of inverter output.And this concussion amplitude will be with injustice
Weigh load increase and increase, it may be assumed that iNBigger, it is bigger that mid-point voltage shakes amplitude.When the control of enabled mid-point voltage, and with difference
When switching frequency enables middle line bridge arm, midpoint concussion voltage magnitude can significantly be reduced.50kHz is respectively adopted in Fig. 5
Identical current in middle wire i is controlled with 10kHzNWhen, midpoint concussion voltage magnitude can be controlled within 5V.And only difference
When being low frequency 10kHz, the ripple of mid-point voltage is larger.But its output quality that will not influence three-phase alternating voltage, more will not
Influence the selection of split capacitor pressure voltage.Therefore, the middle line bridge arm of the system is constructed using the Si-IGBT of cheaper, no
The cost of system can only be reduced.And it when opening with shutdown, can be dropped with the switching speed of 10kHz or more low frequency control pipe
Low switching losses improve the working efficiency of total system.Middle line traffic control measured waveform is referring to Fig. 8.
For those skilled in the art, under the premise of not departing from principle belonging to the present invention, may be used also
To make several improvements and modifications, these modifications and embellishments should also be considered as the scope of protection of the present invention.
