Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each embodiment of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.
A better embodiment of the present utility model relates to a kind of power hardware in ring test system, concrete structure as shown in Figure 1, comprises: equipment to be tested, controller group, simulator, convertor equipment, impedance 203, AC-DC converter (AC/DC), current sensor 201, first power apparatus and the second power apparatus.
Wherein, the second power apparatus is used for simulated power source, is all connected with simulator, convertor equipment.Wherein, power source both can be battery, also can be other power sourcing equipment such as super capacitor.The second power apparatus and simulator is used to come common simulated power source to feeding electric motors, therefore can set freely the voltage of power source, and real power source cannot realize this function, breach the limitation of hardware-in―the-loop test system in prior art.And, the operating instability of power supply can also be avoided, and the danger produced in power supply operation, security of system is high.
In the present embodiment, simulator in the upper realization of industrial computer (industrial control computer), and is connected by interface with the first power apparatus.The realistic model of controlled plant is preserved in simulator.When testing, simulator Dynamic simulation model, simulates each controlled plant at signal level, and exports the weak electric signal representing each controlled plant characteristic.Wherein, in the hardware-in―the-loop test of hybrid power whole vehicle controller, controlled plant comprises: motor, DC load equipment, AC load equipment and power source, simulator respectively at signal level simulated machine, DC load equipment, AC load equipment and power source, and exports the weak electric signal of simulation to the first power apparatus and the second power apparatus.
In industrial computer, simulator carrys out simulated machine according to motor model and runs, the ruuning situation of reaction motor.Such as, when IGBT (insulated gate bipolar transistor) driving circuit, motor should produce great electric current, exports how many moments of torsion.But electric machine controller itself is power device, built-in capacitance and large-scale power device, must be connected with power apparatus, and therefore, industrial computer can not meet testing requirement.Therefore, need power amplifier device to simulate required power, and the power of required output is instructed by industrial computer.
In the present embodiment, the first power apparatus comprises the first power amplifier, the second power amplifier and the 3rd power amplifier.Wherein, simulator exports the weak electric signal of simulated machine, DC load equipment, AC load equipment 204 to the first power amplifier, the second power amplifier and the 3rd power amplifier respectively.First power amplifier, the second power amplifier and the 3rd power amplifier, according to the weak electric signal received, are forceful electric power signal according to the scale amplifying preset, at power level simulated machine, DC load equipment, AC load equipment 204 respectively.Specifically, first power apparatus receives the control signal from simulator by communication interface, and the voltage preset is exported according to control signal, thus realize the object changing equipment working condition to be tested, under different working conditions, complete the standardized test of Devices to test various aspects.Like this, when testing, the first power amplifier, the second power amplifier and the 3rd power amplifier can electric current that is virtually reality like reality, voltage change procedure, and directly can be connected with convertor equipment, to breach power of test of the prior art.Run by real electric current and voltage and can find out the operation troubles that high-voltage operation process is potential, as short circuit phenomenon, open fault, superpressure and under-voltage phenomenon etc., the processing power of HCU is tested, shorten the HCU construction cycle, improve efficiency.Traditional approach just can only can carry out these tests after having HCU product, and then rectifies and improves, and efficiency is much lower.
The circuit structure of the first power amplifier, the second power amplifier as shown in Figure 3, the circuit structure of the 3rd power amplifier as shown in Figure 4, wherein, 301 is IGBT, and 302 is direct current reactor, 303 is electric capacity of voltage regulation, 304 is even resistance, and 305 is output filter, and 401 is diode, the positive pole of DC+ and DC/DC output terminal is connected, and the negative pole of DC-and DC/DC output terminal is connected.
