Noun according to the present invention is explained first：
Super capacitor, be different from traditional electrochmical power source, be one kind between traditional capacitor and battery, have it is special
The power supply of performance relies primarily on electric double layer and Redox pseudocapacitance charge storage electric energy.But it is not sent out in the process of its energy storage
Biochemical reaction, this thermal energy storage process are reversible, also just because of this ultracapacitor can be hundreds thousand of times with repeated charge.Its
Basic principle is all the double electricity formed using activated carbon porous electrode and electrolyte as the double layer capacitor of other types
Layer structure obtains the capacity of super large.
Permanent magnetism trailer system is third generation rail traffic traction technique.Permanent magnetism trailer system has high efficiency, high power close
The significant advantage of degree.
Permanent magnetism trailer system is the dynamical system of rail vehicle, by traction convertor and permanent magnet traction motor two large divisions's group
At traction convertor is for driving permanent magnet traction motor, so that the permanent magnet traction motor draws rail vehicle.
Important parameter one of of the back-emf as permanent magnet traction motor, size will influence motor so that entire permanent magnetism is led
Draw the runnability of motor.
First, if back-emf is larger when rail vehicle coasting, and traction invertor DC side cannot fully absorb regeneration
Energy causes DC side overvoltage, the value of voltage to be more than insulated gate bipolar transistor (Insulated in traction invertor
Gate Bipolar Transistor, abbreviation IGBT) pressure voltage, then IGBT is possible to be burned out.
Secondly, if winding back emf is more than DC voltage, anti-paralleled diode of the electric current through traction invertor
Conducting, will generate regenerative braking, this is also not permitted in actual conditions.
Again, if desired motor puts into operation again, then higher back-emf can be that input brings difficulty again.
Finally, if traction invertor breaks down, such as short-circuit between phase and phase, then back-emf meeting when vehicle coasting
Expand influence of the failure to entire trailer system.
Permanent magnetism trailer system in the related technology.When vehicle coasting, for reduce back-emf it is excessively high caused by influence or adopt
Weak magnetic is taken to reduce the back-emf of traction electric machine ontology or contactor is added between traction invertor and traction electric machine.Fig. 1
It is the structural schematic diagram of existing permanent magnetism trailer system.As shown in Figure 1, when vehicle high-speed inertia, contactor is closed, and waits for vehicle vehicle
After speed reduces, vehicle opens contactor again when need to draw；When vehicle braking, braking energy is generated by traction electric machine and is fed back to straight
Galvanic electricity net side, is absorbed by braking resistor.
In said program, if when vehicle high-speed coasting put into contactor, the belt speed when contactor is closed throw again and compared with
Big problem；In addition back-emf is affected to the performance of motor, it is too big or it is too small motor can all be had an impact, take weak magnetic come
The back-emf for reducing traction electric machine ontology, also has bigger difficulty for design of electrical motor.
In addition, permanent magnet traction motor when vehicle inertia is as generator, energy does not make full use of.
