Description of the drawings
Fig. 1 is the electrical block diagram of the system for Test driver electric machine controller of one embodiment of the invention.
Specific implementation mode
It is of the invention to reach the technical approach and effect that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Specific implementation mode, structure, feature and its effect of the present invention is described in detail as after in accompanying drawings and embodiments.
As shown in Figure 1, the system for Test driver electric machine controller of one embodiment of the invention includes super capacitor
C1, charger, transformer T, filter capacitor C2, IPU (drive motor controller) and fairing R.
The input power of charger is civilian AC220V power supplys, is exported as DC voltage, the DC voltage range of output can
It is configured according to the normal working voltage of IPU, setting principle is to be not higher than IPU highests not less than the minimum operating voltages of IPU
Operating voltage.Charger is connected with super capacitor C1, in test offline without IPU for charging to super capacitor C1, is
Test provides an initial driving force.Further, since will appear energy loss in the offline tests of progress IPU, charger can also be mended
Fill the energy of damage.
Super capacitor C1 is formed by multiple super capacitor monomer connection in series-parallel, and drive motor controller two input terminal phases
Even, for providing test voltage for drive motor controller proper testing process.Super capacitor has the charge and discharge time fast, efficiency
High feature.After inputting a large power test voltage to drive motor controller, drive motor controller will surpass super capacitor
The direct current that grade capacitance provides is converted into three-phase alternating current U/V/W.Each phase alternating current connects with a transformer T-phase, transformer T
Primary with the secondary coil turn ratio be 1:1, electrical isolation can be carried out to U/V/W three-phase alternating currents, and be avoided that change in this way
Coupled voltages are generated between depressor, influence system worked well.Three-phase voltage after electrical isolation is filled with a rectification respectively again
It sets R to be connected, to be rectified into DC voltage.Output voltage after rectification is connected in parallel to filter capacitor C2 and is simply filtered
Wave gives super capacitor C1 chargings again later.Calculate the input power that super capacitor C1 is supplied to drive motor controller again later
It can determine that drive motor controller is functional, otherwise if it is consistent with output power of the drive motor controller after rectified
It can determine that drive motor controller performance is bad.
Its specifically used mode is as follows:When without new product IPU off-line tests, open charger be super capacitor C1 into
Row charging turns off charger when the voltage of super capacitor rises to the rated voltage of its setting.When carrying out under new product IPU
When line detects, super capacitor C1 provides major impetus source for IPU normal works, and the direct current of super capacitor is converted by IPU
After become U/V/W three-phase alternating currents, then carry out electrical isolation, the electricity after electrical isolation per mutually passing through isolating transformer T respectively
Pressure carries out rectification by fairing R becomes direct current, through filter capacitor C2 after often the DC voltage after commutating phase is connected in parallel
It is simply filtered, which finally connect with the positive and negative anodes of super capacitor, charges for super capacitor, and super capacitor
Power source is provided for the normal work of IPU again simultaneously, to realize the energy regenerating of entire test process.During the test by
In each module efficiency it is not possible that being 100%, therefore certain loss is had in energy circulation test process, charger is lucky at this time
The loss of this sub-fraction is made up, the normal work of test system is maintained.
In conclusion since super capacitor C1 can provide large power test voltage for drive motor controller, by sentencing
Disconnected super capacitor C1 be supplied to the input power of drive motor controller and drive motor controller rectified after output power
Whether the quality of the performance of drive motor controller unanimously can determine whether, and the rectified device of the output voltage of drive motor controller
After can charge to super capacitor, be used for Test driver motor to realize the recycling of energy, therefore through the invention
The system of controller can to drive motor controller carry out large power test, and the electric energy of input can be recycled to
Testing cost can be reduced.
