6 FAQs about [Inverter output power measurement]

How is the efficiency of an inverter determined?

The efficiency specified for the inverter is determined using a high-precision measuring process and represents the ratio of the output power to the input power during nominal conditions. These specifications are also verified by independent testing institutes.

How are currents and voltages measured in a pulse width modulated inverter?

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.

What is a pulse width modulated inverter?

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.

How to calculate instantaneous power delivered by pulse width modulated inverter?

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.

What is a measuring device in an inverter?

Measuring devices are integrated into the inverter. These devices ensure the proper system management of the inverter. The inverter's task is to determine the operating point along with the maximum yield.

How to calculate inverter voltage?

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)
