Note 2: A nearly infinite value is shown in a no-conduction state.
However, the value may not be infinite if the momentary conduction occurs through the influence
of the smoothing capacitor
The value shown ranges from a few to a few dozen
Ω
in a conduction state.
The Inverter or converter is in good shape if the values from various parameters are nearly equal,
though they are not consistent depending on the types of elements or testers.
Note 3: The regenerative braking circuit is provided for Inverters with a capacity of 22 kW or lower.
