Embodiment
Below in conjunction with accompanying drawing, integrated form onboard charger of the present invention is described in further detail.
As shown in Figure 1, high tension battery 1 bus is connected with electric machine controller 2 bus.Electric machine controller forms 3 pairs of half-bridges by 6 switching tubes, each paralleled power switches diode.By realizing inversion to three groups of half-bridge sequencing control.
As shown in Figure 2 and Figure 3, rectifier bridge D7 is connected with filter capacitor C2 after carrying out rectification to civil power.The positive pole of filter capacitor C2 is connected to the central point of motor three groups of windings, and the negative pole of filter capacitor C2 is connected with bus negative pole (BUS-) by the first rectifier switch pipe Q7.Bus negative pole is connected with filter capacitor C2 positive pole by the 8th diode D8.This kind of connection forms three road circuit, respectively: the first inductance L 1 and the first switching tube Q1, second switch pipe Q2; Second inductance L 2 and the 3rd switching tube Q3, the 4th switching tube Q4; 3rd inductance L 3 and the 5th switching tube Q5, the 6th switching tube Q6.These three groups of circuit can alternation, and with the first rectifier switch pipe Q7, the 8th diode D8 forms BUCK-BOOST circuit.
Alternating current input comes in connect EMI filter circuit, after rectifier bridge rectification, industrial-frequency alternating current is become the direct current of steamed bun waveshape.When charging is required, closing relay first relay S1 and the second relay S2 then can realize charging.If do not need charging, disconnect relay first relay S1 and the second relay S2, then charging circuit and controller are in off-state, do not affect controller and work independently.When charge power is larger, can work by three groups of circuit simultaneously.
As shown in Figure 4, be described with the circuit that the first inductance L 1 and the first switching tube Q1, second switch pipe Q2, the first rectifier switch pipe Q7, the 8th diode D8 are formed, other two-way circuit are similar for the sequential chart of switching tube.
When second switch pipe Q2 and the first rectifier switch pipe Q7 conducting simultaneously, first inductance L 1 above institute's making alive is filter capacitor C2 voltage, when second switch pipe Q2 and the first rectifier switch pipe Q7 turns off, the first inductance L 1 realizes afterflow by the first diode D1, the first electric capacity C1 and the 8th diode D8.Now the first inductance L 1 making alive is high voltage electric storage cell voltage Vo.Assuming that filter capacitor C2 both end voltage is Vin, in a switch periods, the ratio in second switch pipe Q2 and the first rectifier switch pipe Q7 ON time shared total cycle is D (duty ratio), according to voltage-second balance, then has following expression to set up:
Wherein: T is the cycle, L is the first inductance L 1 inductance value.
Can obtain after arrangement:
Can show that circuit structure is BUCK-BOOST circuit thus, can realize buck, output voltage range is wide, well realizes charging to high tension battery.
Fig. 5, Fig. 6 provide the way of realization with synchronous rectification, carry out synchronous rectification, thus raise the efficiency further by the second rectifier switch pipe Q8 in parallel to the 8th diode D8.Be described with the circuit that the first inductance L 1 and the first switching tube Q1, second switch pipe Q2, the first rectifier switch pipe Q7, the 8th diode D8 are formed, when charge power is larger, three tunnels work together, then the 8th diode D8 loss is larger, therefore by switching tube second rectifier switch pipe Q8, synchronous rectification is carried out to the 8th diode D8, raising efficiency, reduces the 8th diode D8 loss.
The present invention also provides a kind of automobile comprising integrated form onboard charger.
Below illustrate the preferred embodiment of the invention, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent changes under the prerequisite without prejudice to the invention spirit
