The currents and voltages are measured in all three lines. Despite the pulsed voltage of the pulse width modulated inverter, the current is still approximately sinusoidal. Therefore, the current signal is used to derive the cycle time for mean-value calculation in the power measurement.
Innovative measuring instruments are needed to be able to test and optimize the drive train of an electric vehicle. They must enable both highly accurate power measurements and calculation of various intermediate values. A pulse width modulated inverter converts a DC voltage into an AC voltage with variable frequency and amplitude.
The instantaneous power delivered by the pulse width modulated inverter can be calculated with these star voltages and currents (i1, i2, i3). (3.01) Fig. 3.2: Diagram showing a power measurement with an artificial star point Fig. 3.3 shows the result of a measurement with an artificial star point.
The inverter voltages eνM with ν = 1, 2, 3, according to the corresponding control signal, can take on the value +Ud /2 with Sν = 1 or the voltage value -Ud /2with Sν = 0. (2.01) To calculate the line voltages in the machine, first the mesh equations are set up: (2.02)
The total effective power delivered by the pulse width modulated inverter is determined by calculating the mean value of the instantaneous power. Equation 3.02 shows the procedure in Perception. (3.02) The apparent power S is the product of the current RMS value and the voltage RMS value.
Fig. 3.3 shows the result of a measurement with an artificial star point. In this case, the pulse width modulated inverter supplies an asynchronous machine. The currents and voltages are measured in all three lines. Despite the pulsed voltage of the pulse width modulated inverter, the current is still approximately sinusoidal.
