Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model integrated form onboard charger is described in further detail.
As it is shown in figure 1, high tension battery 1 bus is connected with electric machine controller 2 bus.Electric machine controller is formed 3 to half-bridge by 6 switching tubes, one diode of each paralleled power switches.By three groups of half-bridge sequencing contro are realized inversion.
As shown in Figure 2 and Figure 3, it is connected with filter capacitor C2 after rectifier bridge D7 carries out rectification to civil power.The positive pole of filter capacitor C2 is connected to the central point of three groups of windings of motor, 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 L1 and the first switching tube Q1, second switch pipe Q2；Second inductance L2 and the 3rd switching tube Q3, the 4th switching tube Q4；3rd inductance L3 and the 5th switching tube Q5, the 6th switching tube Q6.These three groups of circuit can form BUCK-BOOST circuit with alternation with the first rectifier switch pipe Q7, the 8th diode D8.
Alternating current input comes in connect EMI filter circuit, after rectifier bridge rectification, industrial-frequency alternating current is become the unidirectional current of steamed bread waveshape.When charging is required, closing relay the first relay S1 and the second relay S2 then can realize charging.If need not charging, disconnect relay the first relay S1 and the second relay S2, then charging circuit is off with controller, does not affect controller and works independently.When charge power is bigger, can work by three groups of circuit simultaneously.
The sequential chart of switching tube as shown in Figure 4, illustrates with the circuit that the first inductance L1 and the first switching tube Q1, second switch pipe Q2, the first rectifier switch pipe Q7, the 8th diode D8 are formed, and other two-way circuit are similar to.
When second switch pipe Q2 and the first rectifier switch pipe Q7 simultaneously turns on, above first inductance L1, 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 L1 realizes afterflow by the first diode D1, the first electric capacity C1 and the 8th diode D8.Now the first inductance L1 institute making alive is high voltage electric storage cell voltage Vo.Assuming that filter capacitor C2 both end voltage is Vin, in a switch periods, shared by second switch pipe Q2 and the first rectifier switch pipe Q7 ON time, the ratio in total cycle is D (dutycycle), according to voltage-second balance, then has following expression to set up:
Wherein: T is the cycle, L is the first inductance L1 inductance value.
Can obtain after arrangement:
Therefore deduce that circuit structure is BUCK-BOOST circuit, it is possible to realize buck, output voltage range width, well realize high tension battery is charged.
Fig. 5, Fig. 6 provide the way of realization with synchronous rectification, and the second rectifier switch pipe Q8 carries out synchronous rectification to the 8th diode D8 in parallel, thus improves efficiency further.Illustrate with the circuit that the first inductance L1 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 bigger, three tunnels work together, then the 8th diode D8 loss is bigger, therefore by switching tube the second rectifier switch pipe Q8, the 8th diode D8 is carried out synchronous rectification, raising efficiency, reduces the 8th diode D8 loss.
This utility model also provides for a kind of automobile including integrated form onboard charger.
