The method involves providing a test-bed device with which an exhaust-gas turbo-charger is operated with impulse-loaded fluid mass flow. An operating point of the turbo-charger to be examined is predetermined and is positioned on the test bed device. The operating point is selected from a ...
: Under the function of the PI regulator, the difference between the DC energy storage side charge and discharge current reference value Iref and actual value Idc outputs the modulation depth and compares with the triangle carrier phase to make duty ratio modulation and output control impulse. ...
